// Class performs digitization of Summable digits
-
//
-
// In addition it performs mixing of summable digits from different events.
-
//
-
// For each event two branches are created in TreeD:
-
// "EMCAL" - list of 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
