Detailed Description

The rhs base class.

The RHS class provides the RHS of an equation du/dt = f(u) This is an abstract virtual class that provides a uniform interface to the integrator class. Aside from the standard item functions, derived classes must implement a function dxdt which loads an array with the derivative at a certain time given the time and function value

The array is a void pointer as to allow users to
