+ * 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

+ * 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.
