// 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).
