// $Log: BrDbMagnet.cxx,v $
// Revision 1.1.1.1  2001/06/21 14:55:17  hagel
// Initial revision of brat2
//
// Revision 1.3  2001/06/05 18:40:40  cholm
// Removed BrDbInc.h an all references to it
//
// Revision 1.2  2001/03/22 20:44:37  cholm
// Added protection for NULL TSqlRow in SingleInstance methods, and cleaned
// up a bit of the stuff.
//
// Revision 1.1  2001/01/19 16:30:53  cholm
// Revisited the Run database classes. Deleted old implemtation via BrRun,
// and put in BrDbRun, BrDbFile, BrDbMagnet, BrDbConditions*, and
// BrDbShiftReport. A description will be posted to brahms-dev-l soon.
