ab6a174f 21// Class performs digitization of Summable digits from simulated data
ffa6d63b 22//
61e0abb5 23// In addition it performs mixing of summable digits from different events.
24//
25// For each event two branches are created in TreeD:
26// "EMCAL" - list of digits
27// "AliEMCALDigitizer" - AliEMCALDigitizer with all parameters used in digitization
28//
29// Note, that one cset title for new digits branch, and repeat digitization with
30// another set of parameters.
31//
32// Examples of use:
33// root[0] AliEMCALDigitizer * d = new AliEMCALDigitizer() ;
34// root[1] d->ExecuteTask()
35// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
36// //Digitizes SDigitis in all events found in file galice.root
37//
38// root[2] AliEMCALDigitizer * d1 = new AliEMCALDigitizer("galice1.root") ;
39// // Will read sdigits from galice1.root
40// root[3] d1->MixWith("galice2.root")
41// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
42// // Reads another portion of sdigits from galice2.root
43// root[3] d1->MixWith("galice3.root")
44// // Reads another portion of sdigits from galice3.root
45// root[4] d->ExecuteTask("deb timing")
46// // Reads SDigits from files galice1.root, galice2.root ....
47// // mixes them and stores produced Digits in file galice1.root
48// // deb - prints number of produced digits
49// // deb all - prints list of produced digits
50// // timing - prints time used for digitization
