This directory MMS/mdl/arm2d/armsim contains a C/C++ interface for the 2D
arm model in the parent directory.

The interface consists of a single function armsim, which simulates the system
over a finite time interval.  Constant muscle stimulation levels and joint moments
will be applied during this time interval.

For a muscle stim policy, keep joint moments zero.

See armsim.h for function prototype.
