/*****************************************************************************
 * $Log: StEmcMappingDb.h,v $
 * Revision 1.4  2009/02/01 17:34:52  kocolosk
 * more caching and optimization.
 *
 * Last StEmcMapping commit was bad and left header, implementation
 * inconsistent.  This commit fixes the AutoBuild.
 *
 * Revision 1.1  2009/01/08 02:16:19  kocolosk
 * move StEmcMappingDb/StEmcDecoder to StEmcUtil/database
 *
 * Revision 2.2  2009/01/02 03:34:34  kocolosk
 * use default date==20330101 like St_db_Maker to suppress spurious error msgs
 *
 * Revision 2.1  2008/12/05 19:05:32  kocolosk
 * new DB-backed implementation of StEmcDecoder
