Moved SIM_test_ip and a couple of other sims that depend on the same model set
to a new test directory. I'm doing a couple of sims at a time.

Added a 3 wheeled car example from the ODE demos. I collapsed all of the separate classes
handling the world, objects, and drawings into a single class. Each world is different
and just including that with the objects for these simple examples is easier. Same goes
for the drawing.

Took the ODE bouncing ball tutorial sim and interfaced it within Trick. Created classes to handle
interfacing with ODE and the DrawStuff graphics that comes with ODE. Created classes
to contain the ball and the drawstuff graphics for the ball.

Changed all header file once include variables to follow the same naming
convention and not start with any underscores. Also deleted old
incorrect copyright notices. Also removed $Id: tags from all files.
Fixes#14. Fixes#22.
