a435f763 9// Class that performs digitization of Summable digits from simulated data
10//
11// In addition it performs mixing of summable digits from different events.
12//
13// For each event two branches are created in TreeD:
14// "EMCAL" - list of digits
15// "AliEMCALDigitizer" - AliEMCALDigitizer with all parameters used in digitization
16//
17// Note, that one cset title for new digits branch, and repeat digitization with
18// another set of parameters.
