// Class performs digitization of Summable digits from simulated data
//
-// In addition it performs mixing of summable digits from different events.
+// In addition it performs mixing/embedding of summable digits from different events.
//
-// For each event two branches are created in TreeD:
+// For each event 3 branches are created in TreeD:
// "EMCAL" - list of digits
+// "EMCALTRG" - list of trigger digits
// "AliEMCALDigitizer" - AliEMCALDigitizer with all parameters used in digitization
//
-// Note, that one cset title for new digits branch, and repeat digitization with
-// another set of parameters.
//
-// Examples of use:
-// root[0] AliEMCALDigitizer * d = new AliEMCALDigitizer() ;
-// root[1] d->ExecuteTask()
-// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
-// //Digitizes SDigitis in all events found in file galice.root
-//
-// root[2] AliEMCALDigitizer * d1 = new AliEMCALDigitizer("galice1.root") ;
-// // Will read sdigits from galice1.root
-// root[3] d1->MixWith("galice2.root")
-// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
-// // Reads another portion of sdigits from galice2.root
-// root[3] d1->MixWith("galice3.root")
-// // Reads another portion of sdigits from galice3.root
-// root[4] d->ExecuteTask("deb timing")
-// // Reads SDigits from files galice1.root, galice2.root ....
-// // mixes them and stores produced Digits in file galice1.root
-// // deb - prints number of produced digits
-// // deb all - prints list of produced digits
-// // timing - prints time used for digitization
