-//  Task Class for making SDigits in EMCAL      
-//                  
+// 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
