// MMcTrig
//    
// This class handles and contains the MonteCarlo information
// with which the events have been generated
// This information exists for each event.
//
// This the second version of this output class. Old root files, which have
// a previous version of this class, are still compatibles and can be used.
// But of course, you can no try to get infromatino in these old files about
// the new data members.
//
// The fPixelsFirst array has been increased from 273 (which was the trigger 
// zone) to 577 (which is the full Camera)
