// 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
