//======================================================================
// Class PndEmcTwoCoordIndex
//
//       Software developed for the BaBar Detector at the SLAC B-Factory.
// Adapted for the PANDA experiment at GSI              
//              
// Class to hold coordinate and index information
// for system in which two co-ordinates specifies a channel uniquely.
// (Simplified version of class taken from BABAR framework)
// It is convenient to use 2-coordinate index to describe barel part of EMC
// to search for neigbour crystals in clustering algorithms
//
