// This is a class that makes SDigits out of Hits
// A Summable Digits is the sum of all hits originating 
// from one in one tower of the EMCAL 
// A threshold for assignment of the primary to SDigit is applied 
//
// SDigits need to hold the energy sum of the hits, but AliEMCALDigit
// can (should) only store amplitude.  Therefore, the SDigit energy is
// "digitized" before being stored and must be "calibrated" back to an
// energy before SDigits are summed to form true Digits
