Detailed Description

A class which integrates the equations of motion forward one step in time.

The integration method is based on a 4th Order Runge-Kutta integrator adapted from one given by Atkinson, L.V., et al, "Numerical Methods with Fortran 77.", pp. 310-322, Addison-Wesley Publishing Company, 1989.

The user must supply a pointer to an rdModel on construction.
