NAME:     CaloClusterCorrection.h
PACKAGE:  offline/Calorimeter/CaloClusterCorrection
 
AUTHORS:  H. Ma, S. Rajagopalan
CREATED:  Dec  1999
 
PURPOSE:  Base class: CaloClusterProcessor
          Individual cluster correction classes inherit from this class 
          and use the "set*" methods to correct the CaloCluster objects
 
          execute(CaloCluster *) method to be implemented 
          in the derived class
          
 
Updated:  May 10, 2000    (SR, HM)
          Migrated to Athena Framework from PASO
 
Updated:  Jan 3, 2001    (HM)
          QA.
Updated:  May 2001, (SR) Move to StoreGate
 
Updated:  May 5, 2004    (Sven Menke)
      base class changed from algo to tool
 
Updated:  January, 2005    (MB)
          Move to Calorimeter/CaloClusterCorrection.
 
Updated:  February, 2006 (DLelas)
          New method added:
          "makeCorrectionOnClusCollection(CaloClusterContainer *clusColl)"
          Which enables corrections to be applied to a whole
          CaloCluster collection. It is needed by SW cell weights
          calculation.
