+ 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.
