//_________________________________________________________________________
//  Utility Class for handling Raw data
//  Does all transitions from Digits to Raw and vice versa, 
//  for simu and reconstruction
//
//  Note: the current version is still simplified. Only 
//    one raw signal per digit is generated; either high-gain or low-gain
//    Need to add concurrent high and low-gain info in the future
//    No pedestal is added to the raw signal.
