// Description:
//	Class PndEmcExpClusterSplitter.
//      Concrete implementation of EmcAbsClusterSplitter which splits
//      on the basis of exponential distance from the bump centroid.
//
// Environment:
//	Software developed for the BaBar Detector at the SLAC B-Factory.
//
// Adapted for the PANDA experiment at GSI
