NAME:     CaloCellContainer.h
PACKAGE:  offline/Calorimeter/CaloRec
 
AUTHORS:  S. Rajagopalan
CREATED:  April 2001
 
PURPOSE:  Container for CaloCell - stored as DataObject in TDS.
MODIFIED: David Rousseau: heavy modification to allow storing all 
          calorimeter cells in one single container
