-// Task Class for making Digits in EMCAL
-//
+// Class that performs digitization of Summable digits from simulated data
+//
+// In addition it performs mixing of summable digits from different events.
+//
+// For each event two branches are created in TreeD:
+// "EMCAL" - list of digits
+// "EMCALTRG" - list of trigger digits
+// "AliEMCALDigitizer" - AliEMCALDigitizer with all parameters used in digitization
+//
//*-- Author: Sahal Yacoob (LBL)
// based on : AliPHOSDigit
+// July 2003 Yves Schutz : NewIO
+// November 2003 Aleksei Pavlinov : Shish-Kebab geometry
+//
+// July 2011 GCB: Digitizer modified to accomodate embedding.
+// Time calibration added. Decalibration possibility of energy and time added
