+	  param_user_name: The param (if any) that the user sees and controls.  This is what

+	  the particular body part would look like without physics.  For example, it may be

+	  the breast gravity.  This param's value should will not be altered, and is only

+	  used as a reference point for the rest position of the body party.  This is usually

+	  a driver param and the param that physics is altering is the driven param.

+	  If this is left blank, that means that the physics is affecting a param that is

+	  not exposed to the user.

+

+	  param_driven_name: The param whose value is actually set by the physics.

+

+	  joint_name: The joint that the body part is attached to.  The joint is

+	  used to determine the orientation (rotation) of the body part.

+

+	  character: The avatar that this physics affects.

+

+	  motion_direction_vec: The direction (in world coordinates) that determines the

+	  motion.  For example, (0,0,1) is up-down, and means that up-down motion is what

+	  determines how this joint moves.

+

+	  controllers: The various settings (e.g. spring force, mass) that determine how

+	  the body part behaves.
