// Description:
//	Class PndEmcOnlineBumpSplitter
//      Implementation of OnlineBumpSplitter which splits clusters based on
//      local maxima, determined in a 0th order approximation, i.e. by looking
//		for the two most energetic digis and checking if they are neighbours.
//	
// Environment:
//	Software developed for the PANDA experiment at GSI.
