Detailed Description

This object is built on the gsl_rng struct and modeled to look like a std::random_device object.

If seed is zero, or is not given, then the default seed specific to the particular random number generator is used.

Idea for Future:: This will likely be completely replaced by the random number generators in the standard library.
