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