	--------------------------------------------------------------

	This actor provides level designers with a method of settings up
	waves in story missions. It is used in conjunction with either
	KFZombieVolumes or KFStoryZombieVolumes.

	note : This class just serves as a front end for level designers
	and a place to declare structs.

    All of the heavy lifting is done in KF_Wave_Controller
