 * # How to replace jQuery methods  by ns methods
 * ## append vs appendNodes
 *
 * #### HTML code before manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <div id="second">And</div>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * #### jQuery manipulation
 *
 *     @example
 *     $( "#second" ).append( "<span>Test</span>" );

 * #### ns manipulation
 *
 *     @example
 *     var context = document.getElementById("second"),
 *         element = document.createElement("span");
 *     element.innerHTML = "Test";
 *     ns.util.DOM.appendNodes(context, element);
 *
 * #### HTML code after manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <div id="second">And
 *             <span>Test</span>
 *         </div>
 *        <div id="third">Goodbye</div>
 *     </div>
 *
 * ## replaceWith vs replaceWithNodes
 *
 * #### HTML code before manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <div id="second">And</div>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * #### jQuery manipulation
 *
 *     @example
 *     $('#second').replaceWith("<span>Test</span>");
 *
 * #### ns manipulation
 *
 *     @example
 *     var context = document.getElementById("second"),
 *         element = document.createElement("span");
 *     element.innerHTML = "Test";
 *     ns.util.DOM.replaceWithNodes(context, element);
 *
 * #### HTML code after manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <span>Test</span>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * ## before vs insertNodesBefore
 *
 * #### HTML code before manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <div id="second">And</div>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * #### jQuery manipulation
 *
 *     @example
 *     $( "#second" ).before( "<span>Test</span>" );
 *
 * #### ns manipulation
 *
 *     @example
 *     var context = document.getElementById("second"),
 *         element = document.createElement("span");
 *     element.innerHTML = "Test";
 *     ns.util.DOM.insertNodesBefore(context, element);
 *
 * #### HTML code after manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <span>Test</span>
 *         <div id="second">And</div>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * ## wrapInner vs wrapInHTML
 *
 * #### HTML code before manipulation
 *
 *     @example
 *     <div>
 *         <div id="first">Hello</div>
 *         <div id="second">And</div>
 *         <div id="third">Goodbye</div>
 *     </div>
 *
 * #### jQuery manipulation
 *
 *     @example
 *     $( "#second" ).wrapInner( "<span class="new"></span>" );
 *
 * #### ns manipulation
 *
 *     @example
 *     var element = document.getElementById("second");
 *     ns.util.DOM.wrapInHTML(element, "<span class="new"></span>");
 *
 * #### HTML code after manipulation

/**
 * #BaseWidget
 * Prototype class of widget
 *
 * ## How to invoke creation of widget from JavaScript
 *
 * To build and initialize widget in JavaScript you have to use method {@link ns.engine#instanceWidget} . First argument for method
 * is HTMLElement, which specifies the element of widget. Second parameter is name of widget to create.
 *
 * If you load jQuery before initializing tau library, you can use standard jQuery UI Widget notation.
 *
 * ### Examples
 * #### Build widget from JavaScript
 *
 *        @example
 *        var element = document.getElementById("id"),
 *            ns.engine.instanceWidget(element, "Button");
 *
 * #### Build widget from jQuery
 *
 *        @example
 *        var element = $("#id").button();
 *
 * ## How to create new widget
 *
 *        @example
 *        (function (ns) {
 *			"use strict";
 *			 *					var BaseWidget = ns.widget.BaseWidget, // create alias to main objects
 *						...
 *						arrayOfElements, // example of private property, common for all instances of widget
 *						Button = function () { // create local object with widget
 *							...
 *						},
 *						prototype = new BaseWidget(); // add ns.widget.BaseWidget as prototype to widget's object, for better minification this should be assign to local variable and next variable should be assign to prototype of object
 *
 *					function closestEnabledButton(element) { // example of private method
 *						...
 *					}
 *					...
 *
 *					prototype.options = { //add default options to be read from data- attributes
 *						theme: "s",
 *						...
 *					};
 *
 *					prototype._build = function (template, element) { // method called when the widget is being built, should contain all HTML manipulation actions
 *						...
 *						return element;
 *					};
 *
 *					prototype._init = function (element) { // method called during initialization of widget, should contain all actions necessary fastOn application start
 *						...
 *						return element;
 *					};
 *
 *					prototype._bindEvents = function (element) { // method to bind all events, should contain all event bindings
 *						...
 *					};
 *
 *					prototype._enable = function (element) { // method called during invocation of enable() method
 *						...
 *					};
 *
 *					prototype._disable = function (element) { // method called during invocation of disable() method
 *						...
 *					};
 *
 *					prototype.refresh = function (element) { // example of public method
 *						...
 *					};
 *
 *					prototype._refresh = function () { // example of protected method
 *						...
 *					};
 *
 *					Button.prototype = prototype;
 *
 *					engine.defineWidget( // define widget
 *						"Button", //name of widget
 *						"[data-role='button'],button,[type='button'],[type='submit'],[type='reset']",  //widget's selector
 *						[ // public methods, here should be list all public method, without that method will not be available
 *							"enable",
 *							"disable",
 *							"refresh"
 *						],
 *						Button, // widget's object
 *						"mobile" // widget's namespace
 *					);
 *					ns.widget.Button = Button;

/**
 * # Page Widget
 * Page is main element of application's structure.
 *
 * ## Default selectors
 * In the Tizen Web UI framework the application page structure is based on a header, content and footer elements:
 *
 * - **The header** is placed at the top, and displays the page title and optionally buttons.
 * - **The content** is the section below the header, showing the main content of the page.
 * - **The footer** is a bottom part of page which can display for example buttons
 *
 * The following table describes the specific information for each section.
 *
 * <table>
 *     <tr>
 *         <th>Section</th>
 *         <th>Class</th>
 *         <th>Mandatory</th>
 *         <th>Description</th>
 *     </tr>
 *     <tr>
 *         <td rowspan="2">Page</td>
 *         <td>ui-page</td>
 *         <td>Yes</td>
 *         <td>Defines the element as a page.
 *
 * The page widget is used to manage a single item in a page-based architecture.
 *
 * A page is composed of header (optional), content (mandatory), and footer (optional) elements.</td>
 *      </tr>
 *      <tr>
 *          <td>ui-page-active</td>
 *          <td>No</td>
 *          <td>If an application has a static start page, insert the ui-page-active class in the page element to speed up the application launch. The start page with the ui-page-active class can be displayed before the framework is fully loaded.
 *
 *If this class is not used, the framework inserts the class automatically to the first page of the application. However, this has a slowing effect on the application launch, because the page is displayed only after the framework is fully loaded.</td>
 *      </tr>
 *      <tr>
 *          <td>Header</td>
 *          <td>ui-header</td>
 *          <td>No</td>
 *          <td>Defines the element as a header.</td>
 *      </tr>
 *      <tr>
 *          <td>Content</td>
 *          <td>ui-content</td>
 *          <td>Yes</td>
 *          <td>Defines the element as content.</td>
 *      </tr>
 *      <tr>
 *          <td>Footer</td>
 *          <td>ui-footer</td>
 *          <td>No</td>
 *          <td>Defines the element as a footer.
 *
 * The footer section is mostly used to include option buttons.</td>
 *      </tr>
 *  </table>
 *
 * All elements with class=ui-page will be become page widgets
 *
 *      @example
 *         <!--Page layout-->
 *         <div class="ui-page ui-page-active">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 *         <!--Page layout with more button in header-->
 *         <div class="ui-page ui-page-active">
 *             <header class="ui-header ui-has-more">
 *                 <h2 class="ui-title">Call menu</h2>
 *                 <button type="button" class="ui-more ui-icon-overflow">More Options</button>
 *             </header>
 *             <div class="ui-content">Content message</div>
 *             <footer class="ui-footer">
 *                 <button type="button" class="ui-btn">Footer Button</button>
 *             </footer>
 *         </div>
 *
 * ## Manual constructor
 * For manual creation of page widget you can use constructor of widget from **tau** namespace:
 *
 *        @example
 *        var pageElement = document.getElementById("page"),
 *            page = tau.widget.page(buttonElement);
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create widget. We recommend get this element by method *document.getElementById*.
 *
 * ## Multi-page Layout
 *
 * You can implement a template containing multiple page containers in the application index.html file.
 *
 * In the multi-page layout, the main page is defined with the ui-page-active class. If no page has the ui-page-active class, the framework automatically sets up the first page in the source order as the main page. You can improve the launch performance by explicitly defining the main page to be displayed first. If the application has to wait for the framework to set up the main page, the page is displayed with some delay only after the framework is fully loaded.
 *
 * You can link to internal pages by referring to the ID of the page. For example, to link to the page with an ID of two, the link element needs the href="#two" attribute in the code, as in the following example.
 *
 *      @example
 *         <!--Main page-->
 *         <div id="one" class="ui-page ui-page-active">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 *         <!--Secondary page-->
 *         <div id="two" class="ui-page">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 * To find the currently active page, use the ui-page-active class.
 *
 * ## Changing Pages
 * ### Go to page in JavaScript
 * To change page use method *tau.changePage*
 *
 *      @example
 *      tau.changePage("page-two");
 *
 * ### Back in JavaScript
 * To back to previous page use method *tau.back*
 *
 *      @example
 *      tau.back();
 *
 * ## Transitions
 *
 * When changing the active page, you can use a page transition.
 *
 * Tizen Web UI Framework does not apply transitions by default. To set a custom transition effect, you must add the data-transition attribute to a link:
 *
 *      @example
 *      <a href="index.html" data-transition="slideup">I'll slide up</a>
 *
 * To set a default custom transition effect for all pages, use the pageTransition property:
 *
 *      @example
 *      tau.defaults.pageTransition = "slideup";
 *
 * ### Transitions list
 *
 *  - **none** no transition.
 *  - **slideup** Makes the content of the next page slide up, appearing to conceal the content of the previous page.
 *
 * ## Handling Page Events
 *
 * With page widget we have connected many of events.
 *
 * To handle page events, use the following code:
 *
 *      @example
 *        <div id="page" class="ui-page">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *         </div>
 *
 *         <script>
 *             var page = document.getElementById("page");
 *             page.addEventListener("Event", function(event) {
 *                 // Your code
 *             });
 *         </script>
 *
 * To bind an event callback on the Back key, use the following code:
 *
 * Full list of available events is in [events list section](#events-list).
 *
 * To bind an event callback on the Back key, use the following code:
 *
 *      @example
 *         <script>
 *             window.addEventListener("tizenhwkey", function (event) {
 *                 if (event.keyName == "back") {
 *                     // Call window.history.back() to go to previous browser window
 *                     // Call tizen.application.getCurrentApplication().exit() to exit application
 *                     // Add script to add another behavior
 *                 }
 *             });
 *         </script>
 *
 * ## Options for Page Widget
 *
 * Page widget hasn't any options.
 *
 * ## Methods
 *
 * To call method on widget you can use tau API:
 *
 *        @example
 *        var pageElement = document.getElementById("page"),
 *            page = tau.widget.page(buttonElement);
 *
 *        page.methodName(methodArgument1, methodArgument2, ...);

 *
 * Samsung Wearable Web UI Framework supports 3 icon css styles:
 *
 *  - ui-icon-detail
 *  - ui-icon-overflow
 *  - ui-icon-selectall
 *
 * ### Disabled
 *
 * If you want to make disabled button, add attribute *disabled* in button tag:
 *
 *      @example
 *      <button class="ui-btn" disabled="disabled">Button disabled</button>
 *
 * ### Inline
 *
 * If you want to make inline button, add class *ui-inline* to button element:
 *
 *      @example
 *      <button class="ui-btn ui-inline">Inline button</button>
 *
 * ### Multiline

 *
 *      @example
 *      <button class="ui-btn ui-multiline">Multiline button</button>
 *
 * ### Color theme
 *
 * To optimize color support for the Samsung Wearable, the following styles below are supported:
 *
 * <table>
 *  <tr>
 *      <th>Class</th>
 *      <th>Default</th>
 *      <th>Press</th>
 *      <th>Disable</th>
 *  </tr>
 *  <tr>
 *      <td>ui-color-red</td>
 *      <td>#ce2302</td>
 *      <td>#dd654e</td>
 *      <td>#3d0a0a</td>
 *  </tr>
 *  <tr>
 *      <td>ui-color-orange</td>
 *      <td>#ed8600</td>
 *      <td>#f0aa56</td>
 *      <td>#462805</td>
 *  </tr>
 *  <tr>
 *      <td>ui-color-green</td>
 *      <td>#64a323</td>
 *      <td>#92be5e</td>
 *      <td>#1e3108</td>
 *  </tr>
 * </table>
 *
 * ### Button Group
 *
 * You can group buttons in columns or rows. The following table lists the supported button column and row classes.
 *
 * <table>
 *  <tr>
 *      <th>Class</th>
 *      <th>Description</th>
 *  </tr>
 *  <tr>
 *      <td>ui-grid-col-1</td>
 *      <td>Defines the button column width as 100% of the screen.</td>
 *  </tr>
 *  <tr>
 *      <td>ui-grid-col-2</td>
 *      <td>Defines the button column width as 50% of the screen.</td>
 *  </tr>
 *  <tr>
 *      <td>ui-grid-col-3</td>
 *      <td>Defines the button column width as 33% of the screen.</td>
 *  </tr>
 *  <tr>
 *      <td>ui-grid-row</td>
 *      <td>Arranges the buttons in a row.</td>
 *  </tr>
 * </table>
 *
 * To implement the button groups, use the following code:
 *
 * #### For columns:
 *
 *      @example
 *      <div class="ui-grid-col-3" style="height:76px">
 *          <button type="button" class="ui-btn">Button Circle</button>
 *          <a href="#" class="ui-btn ui-color-red" >A Button Circle</a>
 *          <input type="button" class="ui-btn ui-color-orange" value="Input Button Circle" />
 *      </div>
 *
 * #### For rows:
 *
 *      @example
 *      <div class="ui-grid-row">
 *          <button type="button" class="ui-btn">Button Circle</button>
 *          <a href="#" class="ui-btn ui-color-red" >A Button Circle</a>
 *          <input type="button" class="ui-btn ui-color-orange" value="Input Button Circle" />

/**
 * # ScrollView Widget
 * Widgets allows for creating scrollable panes, lists, etc.
 *
 * ## Default selectors
 * All elements with _data-role=content attribute or _.ui-scrollview
 * css class will be changed to ScrollView widgets, unless they specify
 * _data-scroll=none attribute.
 *
 * ### HTML Examples
 *
 * #### Data attribute
 *
 *        @example
 *        <div data-role="page">
 *            <div data-role="content"><!-- this will become scrollview //-->
 *                content data
 *            </div>
 *        </div>
 *
 * #### CSS Class
 *
 *        @example
 *        <div data-role="page">
 *            <div class="ui-content"><!-- this will become scrollview //-->
 *                content data
 *            </div>
 *        </div>
 *
 * ## Manual constructor
 *
 * To create the widget manually you can use 2 different APIs, the TAU
 * API or jQuery API.
 *
 * ### Create scrollview by TAU API
 *
 *        @example
 *        <div data-role="page" id="myPage">
 *            <div data-role="content">
 *                page content
 *            </div>
 *        </div>
 *        <script>
 *            var page = tau.widget.Page(document.getElementById("myPage")),
 *                scrollview = tau.widget.Scrollview(page.ui.content);
 *        </script>
 *
 * ### Create scrollview using jQuery API
 *
 *        @example
 *        <div data-role="page" id="myPage">
 *            <div data-role="content">
 *                page content
 *            </div>
 *        </div>
 *        <script>
 *            $("#myPage > div[data-role='content']").scrollview();
 *        </script>
 *
 * ## Options for Scrollview widget
 *
 * Options can be set using data-* attributes or by passing them to
 * the constructor.
 *
 * There is also a method **option** for changing them after widget
 * creation.
 *
 * jQuery mobile format is also supported.
 *
 * ## Scroll
 *
 * This options specifies of a content element should become Scrollview
 * widget.
 *
 * You can change this by all available methods for changing options.
 *
 * ### By data-scroll attribute
 *
 *        @example
 *        <div data-role="page">
 *            <div data-role="content" data-scroll="none">
 *                content
 *            </div>
 *        </div>
 *
 * ### By config passed to constructor
 *
 *        @example
 *        <div class="myPageClass" data-role="page">
 *            <div data-role="content">
 *                content
 *            </div>
 *        </div>
 *        <script>
 *            var contentElement = document.querySelector(".myPageClass > div[data-role=content]");
 *            tau.widget.Scrollview(contentElement, {
 *				"scroll": false
 *			});
 *        </script>
 *
 * ### By using jQuery API
 *
 *        @example
 *        <div class="myPageClass" data-role="page">
 *            <div data-role="content">
 *                content
 *            </div>
 *        </div>
 *        <script>
 *            $(".myPageClass > div[data-role='content']").scrollview({
 *				"scroll": false
 *			});
 *        </script>
 *
 * ## ScrollJumps
 *
 * Scroll jumps are small buttons which allow the user to quickly
 * scroll to top or left
 *
 * You can change this by all available methods for changing options.
 *
 * ### By data-scroll-jump
 *
 *        @example
 *        <div data-role="page">
 *            <div data-role="content" data-scroll-jump="true">
 *                content
 *            </div>
 *        </div>
 *
 * ### By config passed to constructor
 *
 *        @example
 *        <div class="myPageClass" data-role="page">
 *            <div data-role="content">
 *                content
 *            </div>
 *        </div>
 *        <script>
 *            var contentElement = document.querySelector(".myPageClass > div[data-role=content]");
 *            tau.widget.Scrollview(contentElement, {
 *				"scrollJump": true
 *			});
 *        </script>
 *
 * ### By using jQuery API
 *
 *        @example
 *        <div class="myPageClass" data-role="page">
 *            <div data-role="content">
 *                content
 *            </div>
 *        </div>
 *        <script>
 *            $(".myPageClass > div[data-role='content']").scrollview({
 *				"scrollJump": true
 *			});
 *        </script>
 *
 * ## Methods
 *
 * Page methods can be called trough 2 APIs: TAU API and jQuery API
 * (jQuery mobile-like API)

 * - **The content** is the section below the header, showing the main content of the page.
 * - **The footer** is a bottom part of page which can display for example buttons
 *
 * The following table describes the specific information for each section.
 *
 * <table>

 *          <td>If an application has a static start page, insert the ui-page-active class in the page element to speed up the application launch. The start page with the ui-page-active class can be displayed before the framework is fully loaded.
 *
 *If this class is not used, the framework inserts the class automatically to the first page of the application. However, this has a slowing effect on the application launch, because the page is displayed only after the framework is fully loaded.</td>
 *      </tr>
 *      <tr>
 *          <td>Header</td>
 *          <td>ui-header</td>
 *          <td>No</td>
 *          <td>Defines the element as a header.</td>
 *      </tr>
 *      <tr>
 *          <td>Content</td>
 *          <td>ui-content</td>

 *          <td>Defines the element as a footer.
 *
 * The footer section is mostly used to include option buttons.</td>
 *      </tr>
 *  </table>
 *
 * All elements with class=ui-page will be become page widgets
 *
 *      @example
 *         <!--Page layout-->
 *         <div class="ui-page ui-page-active">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 *         <!--Page layout with more button in header-->
 *         <div class="ui-page ui-page-active">
 *             <header class="ui-header ui-has-more">
 *                 <h2 class="ui-title">Call menu</h2>
 *                 <button type="button" class="ui-more ui-icon-overflow">More Options</button>
 *             </header>
 *             <div class="ui-content">Content message</div>
 *             <footer class="ui-footer">
 *                 <button type="button" class="ui-btn">Footer Button</button>
 *             </footer>
 *         </div>
 *
 * ## Manual constructor
 * For manual creation of page widget you can use constructor of widget from **tau** namespace:
 *
 *        @example
 *        var pageElement = document.getElementById("page"),
 *            page = tau.widget.page(buttonElement);
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create widget. We recommend get this element by method *document.getElementById*.
 *
 * ## Multi-page Layout
 *
 * You can implement a template containing multiple page containers in the application index.html file.
 *
 * In the multi-page layout, the main page is defined with the ui-page-active class. If no page has the ui-page-active class, the framework automatically sets up the first page in the source order as the main page. You can improve the launch performance by explicitly defining the main page to be displayed first. If the application has to wait for the framework to set up the main page, the page is displayed with some delay only after the framework is fully loaded.
 *
 * You can link to internal pages by referring to the ID of the page. For example, to link to the page with an ID of two, the link element needs the href="#two" attribute in the code, as in the following example.
 *
 *      @example
 *         <!--Main page-->
 *         <div id="one" class="ui-page ui-page-active">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 *         <!--Secondary page-->
 *         <div id="two" class="ui-page">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *             <footer class="ui-footer"></footer>
 *         </div>
 *
 * To find the currently active page, use the ui-page-active class.
 *
 * ## Changing Pages
 * ### Go to page in JavaScript
 * To change page use method *tau.changePage*
 *
 *      @example
 *      tau.changePage("page-two");
 *
 * ### Back in JavaScript
 * To back to previous page use method *tau.back*
 *
 *      @example
 *      tau.back();
 *
 * ## Transitions
 *
 * When changing the active page, you can use a page transition.
 *
 * Tizen Web UI Framework does not apply transitions by default. To set a custom transition effect, you must add the data-transition attribute to a link:
 *
 *      @example
 *      <a href="index.html" data-transition="slideup">I'll slide up</a>
 *
 * To set a default custom transition effect for all pages, use the pageTransition property:
 *
 *      @example
 *      tau.defaults.pageTransition = "slideup";
 *
 * ### Transitions list
 *
 *  - **none** no transition.
 *  - **slideup** Makes the content of the next page slide up, appearing to conceal the content of the previous page.
 *
 * ## Handling Page Events
 *
 * With page widget we have connected many of events.
 *
 * To handle page events, use the following code:
 *
 *      @example
 *        <div id="page" class="ui-page">
 *             <header class="ui-header"></header>
 *             <div class="ui-content"></div>
 *         </div>
 *
 *         <script>
 *             var page = document.getElementById("page");
 *             page.addEventListener("Event", function(event) {
 *                 // Your code
 *             });
 *         </script>
 *
 * To bind an event callback on the Back key, use the following code:
 *
 * Full list of available events is in [events list section](#events-list).
 *
 * To bind an event callback on the Back key, use the following code:
 *
 *      @example
 *         <script>
 *             window.addEventListener("tizenhwkey", function (event) {
 *                 if (event.keyName == "back") {
 *                     // Call window.history.back() to go to previous browser window
 *                     // Call tizen.application.getCurrentApplication().exit() to exit application
 *                     // Add script to add another behavior
 *                 }
 *             });
 *         </script>
 *
 * ## Options for Page Widget
 *
 * Page widget hasn't any options.
 *
 * ## Methods
 *
 * To call method on widget you can use tau API:
 *
 *        @example
 *        var pageElement = document.getElementById("page"),
 *            page = tau.widget.page(buttonElement);
 *
 *        page.methodName(methodArgument1, methodArgument2, ...);

 * # Popup Widget
 * Shows a pop-up window.
 *
 * The popup widget shows in the middle of the screen a list of items in a pop-up window. It automatically optimizes the pop-up window size within the screen. The following table describes the supported popup classes.
 *
 * ## Default selectors
 * All elements with class *ui-popup* will be become popup widgets.
 *
 * The pop-up window can contain a header, content, and footer area like the page element.
 *
 * To open a pop-up window from a link, use the data-rel attribute in HTML markup as in the following code:
 *
 *      @example
 *      <a href="#popup" class="ui-btn" data-rel="popup">Open popup when clicking this element.</a>
 *
 * The following table shows examples of various types of popups.
 *
 * The popup contains header, content and footer area

 *                    Turning on Power
 *                    saving mode will
 *                    limit the maximum
 *                    per
 *                </div>

 *             </div>
 *         </div>
 *     </div>
 *
 * #### Popup with no header and footer
 *
 *      @example
 *         <div id="listNoTitleNoBtnPopup" class="ui-popup">
 *             <div class="ui-popup-content" style="height:294px; overflow-y:scroll">
 *                 <ul class="ui-listview">
 *                     <li><a href="">Ringtones 1</a></li>
 *                     <li><a href="">Ringtones 2</a></li>
 *                     <li><a href="">Ringtones 3</a></li>

 *             <div class="ui-popup-content">Saving contacts to sim on Samsung</div>
 *         </div>
 *
 * ### Create Option popup
 *
 * Popup inherits value of option positionTo from property data-position-to set in link.
 *
 *        @example
 *        <!--definition of link, which opens popup and sets its position-->
 *        <a href="#popupOptionText" data-rel="popup"  data-position-to="origin">Text</a>
 *        <!--definition of popup, which inherites property position from link-->
 *        <div id="popupOptionText" class="ui-popup">
 *            <div class="ui-popup-content">
 *                <ul class="ui-listview">
 *                <li><a href="#">Option 1</a></li>
 *                <li><a href="#">Option 2</a></li>
 *                <li><a href="#">Option 3</a></li>
 *                <li><a href="#">Option 4</a></li>
 *                </ul>
 *            </div>
 *        </div>
 *
 * ### Opening and closing popup
 *
 * To open popup from "a" link using html markup, use the following code:
 *
 *        @example
 *      <div class="ui-page">
 *          <header class="ui-header">
 *              <h2 class="ui-title">Call menu</h2>
 *          </header>
 *          <div class="ui-content">
 *              <a href="#popup" class="ui-btn" data-rel="popup" >Open Popup</a>
 *          </div>
 *
 *          <div id="popup" class="ui-popup">
 *               <div class="ui-popup-header">Power saving mode</div>
 *                   <div class="ui-popup-content">
 *                       Turning on Power
 *                       saving mode will
 *                       limit the maximum
 *                       per
 *                   </div>
 *               <div class="ui-popup-footer">
 *               <button id="cancel" class="ui-btn">Cancel</button>
 *           </div>
 *       </div>
 *
 *  To open the popup widget from JavaScript use method *tau.openPopup(to)*
 *
 *          @example
 *          tau.openPopup("popup")
 *
 *  To close the popup widget from JavaScript use method *tau.openPopup(to)*
 *
 *          @example
 *          tau.closePopup("popup")
 *
 * To find the currently active popup, use the ui-popup-active class.
 *
 * To bind the popup to a button, use the following code:
 *
 *      @example
 *         <!--HTML code-->
 *         <div id="1btnPopup" class="ui-popup">
 *             <div class="ui-popup-header">Power saving mode</div>
 *             <div class="ui-popup-content">
 *             </div>
 *             <div class="ui-popup-footer">
 *                 <button id="1btnPopup-cancel" class="ui-btn">Cancel</button>
 *             </div>
 *         </div>
 *         <script>
 *             // Popup opens with button click
 *             var button = document.getElementById("button");
 *             button.addEventListener("click", function() {
 *                 tau.openPopup("#1btnPopup");
 *             });
 *
 *             // Popup closes with Cancel button click
 *             document.getElementById("1btnPopup-cancel").addEventListener("click", function() {
 *                 tau.closePopup();
 *             });
 *         </script>
 *
 * ## Manual constructor
 * For manual creation of popup widget you can use constructor of widget from **tau** namespace:
 *
 *        @example
 *        var popupElement = document.getElementById("popup"),
 *            popup = tau.widget.popup(buttonElement);
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create widget. We recommend get this element by method *document.getElementById*.
 *
 * ## Options for Popup Widget
 *
 * Options for widget can be defined as _data-..._ attributes or give as parameter in constructor.
 *
 * You can change option for widget using method **option**.
 *
 * ## Methods
 *
 * To call method on widget you can use tau API:
 *
 *        @example
 *        var popupElement = document.getElementById("popup"),
 *            popup = tau.widget.popup(buttonElement);
 *
 *        popup.methodName(methodArgument1, methodArgument2, ...);
 *
 * ## Transitions
 *
 * By default, the framework doesn't apply transition. To set a custom transition effect, add the data-transition attribute to the link.
 *
 *        @example
 *        <a href="index.html" data-rel="popup" data-transition="slideup">I'll slide up</a>
 *
 * Global configuration:
 *
 *        @example
 *        gear.ui.defaults.popupTransition = "slideup";
 *
 * ### Transitions list
 *
 * - **none** Default value, no transition.
 * - **slideup** Makes the content of the pop-up slide up.
 *
 * ## Handling Popup Events
 *
 * To use popup events, use the following code:
 *
 *      @example
 *         <!--Popup html code-->
 *         <div id="popup" class="ui-popup">
 *             <div class="ui-popup-header"></div>
 *             <div class="ui-popup-content"></div>
 *         </div>
 *         </div>
 *         <script>
 *             // Use popup events
 *             var popup = document.getElementById("popup");
 *             popup.addEventListener("popupbeforecreate", function() {
 *                 // Implement code for popupbeforecreate event
 *             });
 *         </script>
 *
 * Full list of available events is in [events list section](#events-list).

 * # Popup Widget
 * Shows a pop-up window.
 *
 * The popup widget shows in the middle of the screen a list of items in a pop-up window. It automatically optimizes the pop-up window size within the screen. The following table describes the supported popup classes.
 *
 * ## Default selectors
 * All elements with class *ui-popup* will be become popup widgets.
 *
 * The pop-up window can contain a header, content, and footer area like the page element.
 *
 * To open a pop-up window from a link, use the data-rel attribute in HTML markup as in the following code:
 *
 *      @example
 *      <a href="#popup" class="ui-btn" data-rel="popup">Open popup when clicking this element.</a>
 *
 * The following table shows examples of various types of popups.
 *
 * The popup contains header, content and footer area
 *
 * ###HTML Examples
 *
 * #### Basic popup with header, content, footer
 *
 *        @example
 *        <div class="ui-page">
 *            <div class="ui-popup">
 *                <div class="ui-popup-header">Power saving mode</div>
 *                <div class="ui-popup-content">
 *                    Turning on Power
 *                    saving mode will
 *                    limit the maximum
 *                    per
 *                </div>
 *                <div class="ui-popup-footer">
 *                    <button id="cancel" class="ui-btn">Cancel</button>
 *                </div>
 *            </div>
 *        </div>
 *
 * #### Popup with 2 buttons in the footer
 *
 *      @example
 *         <div id="2btnPopup" class="ui-popup">
 *             <div class="ui-popup-header">Delete</div>
 *             <div class="ui-popup-content">
 *                 Delete the image?
 *             </div>
 *             <div class="ui-popup-footer ui-grid-col-2">
 *                 <button id="2btnPopup-cancel" class="ui-btn">Cancel</button>
 *                 <button id="2btnPopup-ok" class="ui-btn">OK</button>
 *             </div>
 *         </div>
 *
 * #### Popup with checkbox/radio
 *
 * If you want make popup with list checkbox(or radio) just include checkbox (radio) to popup and add class *ui-popup-checkbox-label* to popup element.
 *
 *        @example
 *         <div id="listBoxPopup" class="ui-popup">
 *             <div class="ui-popup-header">When?</div>
 *             <div class="ui-popup-content" style="height:243px; overflow-y:scroll">
 *                 <ul class="ui-listview">
 *                     <li>
 *                         <label for="check-1" class="ui-popup-checkbox-label">Yesterday</label>
 *                         <input type="checkbox" name="checkset" id="check-1" />
 *                     </li>
 *                     <li>
 *                         <label for="check-2" class="ui-popup-checkbox-label">Today</label>
 *                         <input type="checkbox" name="checkset" id="check-2" />

 *                     </li>
 *                 </ul>
 *                 <ul class="ui-listview">
 *                     <li>
 *                         <label for="radio-1" class="ui-popup-radio-label">Mandatory</label>
 *                         <input type="radio" name="radioset" id="radio-1" />

 *                         <input type="radio" name="radioset" id="radio-2" />
 *                     </li>
 *                 </ul>
 *             </div>
 *             <div class="ui-popup-footer">
 *                 <button id="listBoxPopup-close" class="ui-btn">Close</button>
 *             </div>
 *         </div>
 *     </div>
 *
 * #### Popup with no header and footer
 *
 *      @example
 *         <div id="listNoTitleNoBtnPopup" class="ui-popup">
 *             <div class="ui-popup-content" style="height:294px; overflow-y:scroll">
 *                 <ul class="ui-listview">
 *                     <li><a href="">Ringtones 1</a></li>
 *                     <li><a href="">Ringtones 2</a></li>
 *                     <li><a href="">Ringtones 3</a></li>
 *                 </ul>
 *             </div>
 *         </div>
 *
 * #### Toast popup
 *
 *      @example
 *         <div id="PopupToast" class="ui-popup ui-popup-toast">
 *             <div class="ui-popup-content">Saving contacts to sim on Samsung</div>
 *         </div>
 *
 * ### Create Option popup
 *
 * Popup inherits value of option positionTo from property data-position-to set in link.
 *
 *        @example
 *        <!--definition of link, which opens popup and sets its position-->
 *        <a href="#popupOptionText" data-rel="popup"  data-position-to="origin">Text</a>
 *        <!--definition of popup, which inherites property position from link-->
 *        <div id="popupOptionText" class="ui-popup">
 *            <div class="ui-popup-content">
 *                <ul class="ui-listview">
 *                <li><a href="#">Option 1</a></li>
 *                <li><a href="#">Option 2</a></li>
 *                <li><a href="#">Option 3</a></li>
 *                <li><a href="#">Option 4</a></li>
 *                </ul>
 *            </div>
 *        </div>
 *
 * ### Opening and closing popup
 *
 * To open popup from "a" link using html markup, use the following code:
 *
 *        @example
 *      <div class="ui-page">
 *          <header class="ui-header">
 *              <h2 class="ui-title">Call menu</h2>
 *          </header>
 *          <div class="ui-content">
 *              <a href="#popup" class="ui-btn" data-rel="popup" >Open Popup</a>
 *          </div>
 *
 *          <div id="popup" class="ui-popup">
 *               <div class="ui-popup-header">Power saving mode</div>
 *                   <div class="ui-popup-content">
 *                       Turning on Power
 *                       saving mode will
 *                       limit the maximum
 *                       per
 *                   </div>
 *               <div class="ui-popup-footer">
 *               <button id="cancel" class="ui-btn">Cancel</button>
 *           </div>
 *       </div>
 *
 *  To open the popup widget from JavaScript use method *tau.openPopup(to)*
 *
 *          @example
 *          tau.openPopup("popup")
 *
 *  To close the popup widget from JavaScript use method *tau.openPopup(to)*
 *
 *          @example
 *          tau.closePopup("popup")
 *
 * To find the currently active popup, use the ui-popup-active class.
 *
 * To bind the popup to a button, use the following code:
 *
 *      @example
 *         <!--HTML code-->
 *         <div id="1btnPopup" class="ui-popup">
 *             <div class="ui-popup-header">Power saving mode</div>
 *             <div class="ui-popup-content">
 *             </div>
 *             <div class="ui-popup-footer">
 *                 <button id="1btnPopup-cancel" class="ui-btn">Cancel</button>
 *             </div>
 *         </div>
 *         <script>
 *             // Popup opens with button click
 *             var button = document.getElementById("button");
 *             button.addEventListener("click", function() {
 *                 tau.openPopup("#1btnPopup");
 *             });
 *
 *             // Popup closes with Cancel button click
 *             document.getElementById("1btnPopup-cancel").addEventListener("click", function() {
 *                 tau.closePopup();
 *             });
 *         </script>
 *
 * ## Manual constructor
 * For manual creation of popup widget you can use constructor of widget from **tau** namespace:
 *
 *        @example
 *        var popupElement = document.getElementById("popup"),
 *            popup = tau.widget.popup(buttonElement);
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create widget. We recommend get this element by method *document.getElementById*.
 *
 * ## Options for Popup Widget
 *
 * Options for widget can be defined as _data-..._ attributes or give as parameter in constructor.
 *
 * You can change option for widget using method **option**.
 *
 * ## Methods
 *
 * To call method on widget you can use tau API:
 *
 *        @example
 *        var popupElement = document.getElementById("popup"),
 *            popup = tau.widget.popup(buttonElement);
 *
 *        popup.methodName(methodArgument1, methodArgument2, ...);
 *
 * ## Transitions
 *
 * By default, the framework doesn't apply transition. To set a custom transition effect, add the data-transition attribute to the link.
 *
 *        @example
 *        <a href="index.html" data-rel="popup" data-transition="slideup">I'll slide up</a>
 *
 * Global configuration:
 *
 *        @example
 *        gear.ui.defaults.popupTransition = "slideup";
 *
 * ### Transitions list
 *
 * - **none** Default value, no transition.
 * - **slideup** Makes the content of the pop-up slide up.
 *
 * ## Handling Popup Events
 *
 * To use popup events, use the following code:
 *
 *      @example
 *         <!--Popup html code-->
 *         <div id="popup" class="ui-popup">
 *             <div class="ui-popup-header"></div>
 *             <div class="ui-popup-content"></div>
 *         </div>
 *         </div>
 *         <script>
 *             // Use popup events
 *             var popup = document.getElementById("popup");
 *             popup.addEventListener("popupbeforecreate", function() {
 *                 // Implement code for popupbeforecreate event
 *             });
 *         </script>
 *
 * Full list of available events is in [events list section](#events-list).

/**
 * #Drawer
 * Shows a panel that in the sub-layout on the left or right edge of screen.
 *
 * ##Introduction
 *
 * The drawer component is a panel that the application's sub layout on the left or right edge of the screen.
 * This component is hidden most of the time, but user can be opened as swipe gesture from the edge of the screen or click the element that is added event handler,
 * handler has drawer.open() method.
 *
 * Note!
 * We recommend to make handler element.
 * Because if you didn't set the handler, handler was set page element automatically.
 * If you really want to make handler as the page element, you should notice data-drag-edge or dragEdge option value
 * because default value, '1', is whole area of handler element.
 *
 * ## HTML Examples
 *
 *        @example
 *        <div id="drawerPage" class="ui-page">
 *          <header id="contentHeader" class="ui-header">
 *              <h2 class="ui-title">Drawer</h2>
 *          </header>
 *          <div id = "content" class="ui-content">
 *            Drawer
 *          </div>
 *
 *          <!-- Drawer Handler -->
 *          <a id="drawerHandler" href="#Drawer" class="drawer-handler">Drawer Button</a>
 *          <!-- Drawer Widget -->
 *          <div id="drawer" class="ui-drawer" data-drawer-target="#drawerPage" data-position="left" data-enable="true" data-drag-edge="1">
 *              <header class="ui-header">
 *                  <h2 class="ui-title">Left Drawer</h2>
 *              </header>
 *              <div class="ui-content">
 *                  <p>CONTENT</p>
 *              </div>
 *          </div>
 *        </div>
 *
 * ## Manual constructor
 *
 *         @example
 *             (function() {
 *                 var handler = document.getElementById("drawerHandler"),
 *                     page = document.getElementById("drawerPage"),
 *                     drawerElement = document.querySelector(handler.getAttribute("href")),
 *                     drawer = tau.widget.Drawer(drawerElement);
 *
 *                 page.addEventListener( "pagebeforeshow", function() {
 *                         drawer.setDragHandler(handler);
 *                         tau.event.on(handler, "mousedown touchstart", function(e) {
 *                             switch (e.type) {
 *                             case "touchstart":
 *                             case "mousedown":
 *                             // open drawer
 *                             drawer.transition(60);
 *                         }
 *                 }, false);
 *             })();
 *
 * ##Drawer state
 * Drawer has four state type.
 * - "closed" - Drawer closed state.
 * - "opened" - Drawer opened state.
 * - "sliding" - Drawer is sliding state. This state does not mean that will operate open or close.
 * - "settling" - drawer is settling state. 'Settle' means open or close status. So, this state means that drawer is animating for opened or closed state.
 *
 * ##Drawer positioning
 * You can declare to drawer position manually. (Default is left)
 *
 * If you implement data-position attributes value is 'left', drawer appear from left side.
 *
 *        @example
 *        <div class="ui-drawer" data-position="left" id="leftdrawer">
 *
 * - "left" - drawer appear from left side
 * - "right" - drawer appear from right side
 *
 * ##Drawer targeting
 * You can declare to drawer target manually. (Default is Page)
 *
 * If you implement data-drawer-target attribute value at CSS selector type, drawer widget will be appended to target.
 *
 *        @example
 *        <div class="ui-drawer" data-drawer-target="#drawerPage">
 *
 * ##Drawer enable
 * You can declare for whether drawer gesture used or not. (Default is true)
 *
 * If you implement data-enable attribute value is 'true', you can use the drawer widget.
 * This option can be changed by 'enable' or 'disable' method.
 *
 *        @example
 *        <div class="ui-drawer" data-enable="true">
 *
 * ##Drawer drag gesture start point
 * You can declare to drag gesture start point. (Default is 1)
 *
 * If you implement data-drag-edge attribute value is '0.5', you can drag gesture start in target width * 0.5 width area.
 *
 *        @example
 *        <div class="ui-drawer" data-drag-edge="1">

 * # Listview
 * Shows a list view.
 *
 * The list widget is used to display, for example, navigation data, results, and data entries. The following table describes the supported list classes.
 *
 * ## Default selectors
 *
 * Default selector for listview widget is class *ui-listview*.
 *
 * To add a list widget to the application, use the following code:
 *
 * ### List with basic items
 *
 * You can add a basic list widget as follows:
 *
 *      @example
 *         <ul class="ui-listview">
 *             <li>1line</li>
 *             <li>2line</li>
 *             <li>3line</li>
 *             <li>4line</li>
 *             <li>5line</li>
 *         </ul>
 *
 * ### List with link items
 *
 * You can add a list widget with a link and press effect that allows the user to click each list item as follows:
 *
 *      @example
 *         <ul class="ui-listview">
 *             <li>
 *                 <a href="#">1line</a>

/**
 * #Index Scrollbar
 * Shows an index scroll bar with indices, usually for the list.
 *
 * The index scroll bar widget shows on the screen a scrollbar with indices,
 * and fires a select event when the index characters are clicked.
 * The following table describes the supported index scroll bar APIs.
 *
 * ## Manual constructor
 * For manual creation of widget you can use constructor of widget from **tau** namespace:
 *
 *        @example
 *        var indexscrollbarElement = document.getElementById('indexscrollbar'),
 *            indexscrollbar = tau.widget.IndexScrollbar(IndexScrollbar, {index: "A,B,C"});
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create widget.
 * We recommend get this element by method *document.getElementById*. Second parameter is **options**
 * and it is a object with options for widget.
 *
 * To add an IndexScrollbar widget to the application, use the following code:
 *
 *      @example
 *      <div id="foo" class="ui-indexscrollbar" data-index="A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z"></div>
 *      <script>
 *          (function() {
 *              var elem = document.getElementById("foo");
 *              tau.widget.IndexScrollbar(elem);
 *              elem.addEventListener("select", function( event ) {
 *                  var index = event.detail.index;
 *                  console.log(index);
 *              });
 *          }());
 *      </script>
 *
 * The index value can be retrieved by accessing event.detail.index property.
 *
 * In the following example, the list scrolls to the position of the list item defined using
 * the li-divider class, selected by the index scroll bar:
 *
 *      @example
 *         <div id="pageIndexScrollbar" class="ui-page">
 *             <header class="ui-header">
 *                 <h2 class="ui-title">IndexScrollbar</h2>
 *             </header>
 *             <section class="ui-content">
 *                 <div style="overflow-y:scroll;">
 *                     <div id="indexscrollbar1"
 *                          class="ui-indexscrollbar"
 *                          data-index="A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z">
 *                     </div>
 *                     <ul class="ui-listview" id="list1">
 *                         <li class="li-divider">A</li>

 *             </script>
 *         </div>
 *
 * The following example uses the supplementScroll argument, which shows a level 2 index scroll bar.
 * The application code must contain a level 2 index array for each level 1 index character.
 * The example shows a way to analyze list items and create a dictionary (secondIndex) for level 1
 * indices for the index scroll bar, and a dictionary (keyItem) for moving list items at runtime:
 *
 *      @example
 *         <div id="indexscrollbar2" class="ui-indexscrollbar"
 *              data-index="A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z">
 *         </div>
 *         <ul class="ui-listview" id="ibar2_list2">

 * ##Options for widget
 *
 * Options for widget can be defined as _data-..._ attributes or give as parameter in constructor.
 *
 * You can change option for widget using method **option**.
 *
 * ##Methods
 *
 * To call method on widget you can use tau API:
 *
 * First API is from tau namespace:
 *
 *        @example
 *        var indexscrollbarElement = document.getElementById('indexscrollbar'),
 *            indexscrollbar = tau.widget.IndexScrollbar(indexscrollbarElement);
 *
 *        indexscrollbar.methodName(methodArgument1, methodArgument2, ...);

/**
 * # Circular index scroll bar
 * Shows a circular index scroll bar which uses rotary.
 *
 * The circularindexscrollbar component shows on the screen a circularscrollbar with indices.
 * The indices can be selected by moving the rotary.
 * And it fires a select event when the index characters are selected.
 *
 * ## Manual constructor
 * For manual creation of UI Component you can use constructor of component from **tau** namespace:
 *
 *              @example
 *              var circularindexElement = document.getElementById('circularindex'),
 *                  circularindexscrollbar = tau.widget.CircularIndexScrollbar(circularindexElement, {index: "A,B,C"});
 *
 * Constructor has one require parameter **element** which are base **HTMLElement** to create component.
 * We recommend get this element by method *document.getElementById*. Second parameter is **options**
 * and it is a object with options for component.
 *
 * To add an CircularIndexScrollbar component to the application, use the following code:
 *
 *      @example
 *      <div id="foo" class="ui-circularindexscrollbar" data-index="A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z"></div>
 *      <script>
 *          (function() {
 *              var elem = document.getElementById("foo");
 *              tau.widget.CircularIndexScrollbar(elem);
 *              elem.addEventListener("select", function( event ) {
 *                  var index = event.detail.index;
 *                  console.log(index);
 *              });
 *          }());
 *      </script>
 *
 * The index value can be retrieved by accessing event.detail.index property.
 *
 * In the following example, the list scrolls to the position of the list item defined using
 * the li-divider class, selected by the circularindexscrollbar:
 *
 *      @example
 *         <div id="pageCircularIndexScrollbar" class="ui-page">
 *             <header class="ui-header">
 *                 <h2 class="ui-title">CircularIndexScrollbar</h2>
 *             </header>
 *             <div id="circularindexscrollbar"class="ui-circularindexscrollbar" data-index="A,B,C,D,E"></div>
 *             <section class="ui-content">
 *                 <ul class="ui-listview" id="list1">
 *                     <li class="li-divider">A</li>
 *                     <li>Anton</li>
 *                     <li>Arabella</li>

 * # Progress
 * Shows a control that indicates the linear shape progressbar percentage of an on-going operation.
 *
 * The progress widget shows a control that indicates the progress percentage of an on-going operation. This widget can be scaled to fit inside a parent container.
 *
 * ## Default selectors
 *
 * This widget provide three style progress.
 *
 * ### Simple progress bar
 * If you don't implement any class, you can show default progress style
 * To add a progress widget to the application, use the following code:
 *
 *      @example
 *      <progress max="100" value="90"></progress>
 *
 * ### Infinite progress bar
 * If you implement class (*ui-progress-indeterminate*), you can show image looks like infinite move.
 *
 * To add a progress widget to the application, use the following code:
 *      @example
 *      <progress class="ui-progress-indeterminate" max="100" value="100"></progress>
 *
 * ### Progress bar with additional information
 * If you implement div tag that can choose two classes (*ui-progress-proportion* or *ui-progress-ratio*) at progress tag same level, you can show two information (proportion information is located left below and ratio information is located right below)
 *
 * To add a progress widget to the application, use the following code:
 *
 *      @example
 *      <progress max="100" value="50"></progress>
 *      <div class="ui-progress-proportion">00/20</div>
 *      <div class="ui-progress-ratio">50%</div>

/**
 *#Virtual ListView Widget
 * Shows a list view for large amounts of data.
 *
 * In the Web environment, it is challenging to display a large amount of data in a list, such as
 * displaying a contact list of over 1000 list items. It takes time to display the entire list in
 * HTML and the DOM manipulation is complex.
 *
 * The virtual list widget is used to display a list of unlimited data elements on the screen
 * for better performance. This widget provides easy access to databases to retrieve and display data.
 * It based on **result set** which is fixed size defined by developer by data-row attribute. Result
 * set should be **at least 3 times bigger** then size of clip (number of visible elements).
 *
 * To add a virtual list widget to the application follow these steps:
 *
 * ##Create widget container - list element
 *

 &lt;ul id=&quot;vlist&quot; class=&quot;ui-listview ui-virtuallistview&quot;&gt;&lt;/ul&gt;

 *
 * ##Initialize widget
 *
 // Get HTML Element reference
 var elList = document.getElementById("vlist"),
 // Set up config. All config options can be found in virtual list reference
 vListConfig = {
		dataLength: 2000,
		bufferSize: 40,
		listItemUpdater: function(elListItem, newIndex){
			// NOTE: JSON_DATA is global object with all data rows.
			var data = JSON_DATA["newIndex"];
			elListItem.innerHTML = '<span class="ui-li-text-main">' +
												data.NAME + '</span>';
			}
		};
 vlist = tau.widget.VirtualListview(elList, vListConfig);
 *
 * More config options can be found in {@link ns.widget.wearable.VirtualListview#options}
 *
 * ##Set list item update function
 *
 * List item update function is responsible to update list element depending on data row index. If you didn’t
 * pass list item update function by config option, you have to do it using following method.
 * Otherwise you will see an empty list.
 *
 *
 vlist.setListItemUpdater(function(elListItem, newIndex){
		// NOTE: JSON_DATA is global object with all data rows.
		var data = JSON_DATA["newIndex"];
		elListItem.innerHTML = '<span class="ui-li-text-main">' +
									data.NAME + '</span>';
	});
 *
 * **Attention:** Virtual List manipulates DOM elements to be more efficient. It doesn’t remove or create list
 * elements before calling list item update function. It means that, you have to take care about list element
 * and keep it clean from custom classes an attributes, because order of li elements is volatile.
 *
 * ##Draw child elements
 * If all configuration options are set, call draw method to draw child elements and make virtual list work.
 *
 vlist.draw();
 *
 * ##Destroy Virtual List
 * It’s highly recommended to destroy widgets, when they aren’t necessary. To destroy Virtual List call destroy method.
 *
 vlist.destroy();
 *
 * ##Full working code
 *

/**
 * # Selector Component
 *
 * Selector component is special component that has unique UX of Tizen wearable profile.
 * Selector component has been used in more options commonly but If you want to use other situation then you can use
 * this component as standalone component in everywhere.
 * Selector component was consisted as selector element and item elements. You can set the item selector, each items locate degree and radius.
 * Selector component has made layers automatically. Layer has items and you can set items number on one layer.
 * Indicator is indicator that located center of Selector. We provide default indicator style and function.
 * But, If you want to change indicator style and function, you can make the custom indicator and set your indicator for operate with Selector.
 * Indicator arrow is special indicator style that has the arrow. That was used for provide more correct indicate information for user.
 * Also, you can make the custom indicator arrow and set your custom indicator arrow for operate with Selector.
 * Selector provide to control for arrow indicate active item position.
 *
 * ## HTML example
 *
 *          @example
 *              <div class="ui-page ui-page-active" id="main">
 *                  <div id="selector" class="ui-selector">
 *                      <div class="ui-item ui-show-icon" data-title="Show"></div>
 *                      <div class="ui-item ui-human-icon" data-title="Human"></div>
 *                      <div class="ui-item ui-delete-icon" data-title="Delete"></div>
 *                      <div class="ui-item ui-show-icon" data-title="Show"></div>
 *                      <div class="ui-item ui-human-icon" data-title="Human"></div>
 *                      <div class="ui-item ui-delete-icon" data-title="Delete"></div>
 *                      <div class="ui-item ui-x-icon" data-title="X Icon"></div>
 *                      <div class="ui-item ui-fail-icon" data-title="Fail"></div>
 *                      <div class="ui-item ui-show-icon" data-title="Show"></div>
 *                      <div class="ui-item ui-human-icon" data-title="Human"></div>
 *                      <div class="ui-item ui-delete-icon" data-title="Delete"></div>
 *                  </div>
 *              </div>
 *
 * ## Manual constructor
 *
 *          @example
 *              (function() {

 *                  function onClick(event) {
 *                      var activeItem = selector.querySelector(".ui-item-active");
 *                      //console.log(activeItem.getAttribute("data-title"));
 *                  }
 *                  page.addEventListener("pagebeforeshow", function() {
 *                      clickBound = onClick.bind(null);
 *                      tau.widget.Selector(selector);
 *                      selector.addEventListener("click", clickBound, false);
 *                  });
 *                  page.addEventListener("pagebeforehide", function() {
 *                      selector.removeEventListener("click", clickBound, false);
 *                  });
 *              })();
 *
 * ## Options
 * Selector component options
 *
