// Description:
//      Holds map of (layer,wire) -> MdcHit*.  To avoid time wasted in
// building the map, its guts are implemented as a singleton class
// (MdcHitMapGuts); a MdcHitMap can be created, stored in AbsEvent, and
// destroyed every event, but the underlying guts remain the same (they are
// cleared every time an instance is requested).  Or maybe I did it this way
// because I'm bored today.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
