2 * Revised August 26 2009 by Kitto Flora. ODEDynamics.cs replaces
3 * ODEVehicleSettings.cs. It and ODEPrim.cs are re-organised:
4 * ODEPrim.cs contains methods dealing with Prim editing, Prim
5 * characteristics and Kinetic motion.
6 * ODEDynamics.cs contains methods dealing with Prim Physical motion
7 * (dynamics) and the associated settings. Old Linear and angular
8 * motors for dynamic motion have been replace with MoveLinear()
9 * and MoveAngular(); 'Physical' is used only to switch ODE dynamic
10 * simualtion on/off; VEHICAL_TYPE_NONE/VEHICAL_TYPE_<other> is to
11 * switch between 'VEHICLE' parameter use and general dynamics
12 * settings use.
