// Description:
//      Class PndEmcMakeDigi. This class takes array of EmcHit's and produce
// an array of EmcDigis.
// It is convenient to study reconstruction algoritms without
// disturbance from digitization
//
//	 Software developed for the BaBar Detector at the SLAC B-Factory.
// Adapted for the PANDA experiment at GSI
