+ * 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.
