/** @class CbmStsClusterFinder
 ** @brief Abstract base class for STS cluster finding algorithms
 ** @author V.Friese <v.friese@gsi.de>
 ** @version 1.0
 **
 ** Cluster finding means grouping digis supposedly originating from the
 ** same charged track (CbmStsPoint). In the STS modules, this means
 ** clusters are made of digis from neighbouring channels.
 **
 ** A concrete algorithm has to implement the abstract method FindClusters.
 ** This method operates on a CbmStsModule, which holds a list of its digis.
 ** The algorithm has to create objects of type CbmStsCluster and write them
 ** to the output TClonesArray.
