	The CEntity class

	Author: Kevin Hawkins
	Date: 3/29/2001
	Description: The CEntity class is derived from CMD2Model and
			   provides the functionality of an entity in the
			   game world. It holds the current MD2 animation
			   state, the entity angle heading, and the entity's
			   primary sound.
