Portal.h  -  Portals are special constructs which which are used to connect 
			 two Zones in a PCZScene.  Portals are defined by 4 coplanr 
             corners and a direction.  Portals are contained within Zones and 
             are essentially "one way" connectors.  Objects and entities can
			 use them to travel to other Zones, but to return, there must be
			 a corresponding Portal which connects back to the original zone
			 from the new zone.
