! /**
!  * DynamicalSystem is a base class for physics models that can
!  * be solved by numerical integration.  The dynamical variables
!  * are stored in a vector field, and are integrated by an 
!  * associated numerical method (e.g. Runge-Kutta).  The _f()
!  * function of VectorField provides the driving term, which
!  * must be implemented in derived classes.  Implementations of 
!  * _f() typically involve evaluation of one or more BaseDynamics
!  * instances to determine the total force and moment acting on
!  * the body at each instant.
