SimTK multibody dynamics API - shared library

 Simbody is a SimTK toolset providing general multibody dynamics capability,
 that is, the ability to solve Newton's 2nd law F=ma in any set of generalized
 coordinates subject to arbitrary constraints. Simbody is provided as an open
 source, object-oriented C++ API and delivers high-performance,
 accuracy-controlled science/engineering-quality results.
