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

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