0005  *  Description:
0006  *       Class to hold configuration identifier for chambers
0007  *
0008  *  This class was originally defined in
0009  *  CondCore/DTPlugins/interface/DTConfigPluginHandler.h
0010  *  It was moved, renamed, and modified to not be a singleton
0011  *  for thread safety, but otherwise little was changed.
