class AliITSclustererV2: public TObject

            Implementation of the ITS clusterer V2 class

          Origin: Iouri Belikov, CERN, Jouri.Belikov@cern.ch
 This class is no longer used for ITS recosntruction:
 it has been replaced by the AliITSClusterFinderV2SXD classes
 It is still used as mother class by HLT reconstruction
