+// Purpose: An area entity that players must remain in in order to active another entity
+//			Triggers are fired on start of capture, on end of capture and on broken capture
+//			Can either be capped by both teams at once, or just by one
+//			Time to capture and number of people required to capture are both passed by the mapper
