Detailed Description

This is a straightforward translation of the Sundials CPODES C interface into C++.

The class CPodes represents a single instance of a CPODES integrator, and handles the associated memory internally. Methods here are identical to the corresponding CPODES functions (with the "CPode" prefix removed) but are const-correct and use SimTK Vector & Real rather than Sundials N_Vector and realtype.
