Given initial value of the n-dimensional function in y and the derivative in dydx (which must generally be computed beforehand) at the point x, take a step of size h giving the result in yout, the uncertainty at 
in yerr, and the new derivative at in dydx_out using function derivs to calculate derivatives. Implementations which do not calculate yerr and/or dydx_out do not reference these variables so that a blank vec_t can be given. All of the current O2scl implementations allow yout=y and dydx_out=dydx if necessary
