// 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.
// (Based on class from BABAR framework)
