// CAI_Behavior...
//
// Purpose:	The core component that defines a behavior in an NPC by selecting
//			schedules and running tasks
//
//			Intended to be used as an organizational tool as well as a way
//			for various NPCs to share behaviors without sharing an inheritance
//			relationship, and without cramming those behaviors into the base
//			NPC class.
//-----------------------------------------------------------------------------


//-----------------------------------------------------------------------------
// Purpose: Base class defines interface to behaviors and provides bridging
//			methods
//-----------------------------------------------------------------------------
