Subject: Body is now an INSTANTIABLE OBJECT holding only the Group Tree
 Structure and Geometry for the Tank RemoteObject.

Tank now takes advantage of utilizing saved references in Body object.

Tank can now rotate in place (imperfect), as well as rotate the turret (all the way around), and elevate the turret up to +13 * Pi / 32 degrees and down to -Pi / 32 Degrees.

ToDo:
Body: add emitter to barrel for firing
Tank: add keycode to fire
NEWCLASS: Ammunition class
