 * - change from getByType to getByLabel in ECAL TPG,
 *   and make it configurable.
 * - fix problem in the GCT with incorrect labels. Not the ultimate
 *   solution - will probably have to go to many labels.
 *
 * Revision 1.2  2007/02/19 22:07:26  wittich
 * - Added three monitorables to the ECAL TPG monitoring (from GCTMonitor)
 * - other minor tweaks in GCT, etc
