////////////////////////////////////////////////////////////////////////////////
//
// Memory.h
//
//	This file contains assorted memory-oriented routines:
//
//	    Zeros(): fills memory with zeros.
//	    Destroy(): destructs multiple objects in contiguous memory.
//	    CopyToRaw(): copies multiple objects to raw memory.
//	    InitializeRaw(): default constructs mulitple object over raw memory.
//
//	Each of these is a template but specializations are provide for
//	efficiency (which in some cases removes uncessary loops).
