CM is a celestial mechanics simulator with an Intuition interface.
You construct a layout of Bodies and specify various parameters
for the bodies and the simulation.  CM then animates the bodies
according to the laws of gravational attraction ( F = Gm1m2/r^2 ).
Setups may be saved to disk to later re-inact interesting scenarios.
