// Class used to simplify some operations with clusters.                 //
// -Function FillArray fills an array wich contains, for each            //
//  ITS module, an array with the indices of all the clusters detected   //
//  by the module. The indices correspond to the cluster indices in class// 
//  AliITSlayer of AliITStrackerV2.                                      //
//  This function is used in AliITStrackerSA::FindTracks.                // 
// -Function FillArrayLabel fills an array wich contains, for each       //
//  particle label, and for each layer, the information on clusters:     //
//  0 if there is no cluster, 1 if there is a cluster with this label.   //
//  This function is used to define trackable tracks.                    //
