-* Description:
+* Description: This class holds information about a player in a
+* multiplayer game. The model for a remote player is loaded and
+* added onto the aircraft branch of the scene on calling Open.
+* The model is unloaded from the scene when Close is called
+* or the object is deleted. The model's positioning transform is
+* updated by calling SetPosition. The updated position transform
+* is applied to the model on the scene by calling Draw.
