// Class performs digitization of Summable digits (in the PHOS case this is just
// sum of contributions of all primary particles into given cell).
// In addition it performs mixing of summable digits from different events.
// Examples of use:
// root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ;
// root[1] d->ExecuteTask()
// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
// //Digitizes SDigitis in all events found in file galice.root
// //Depending on variable "CONFIG_SPLIT_FILE" reads branches stored in galice.root
// //or in PHOS.SDigits.root
// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("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
//
// For each event two branches are created in TreeD:
// "PHOS" - list of digits
// "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
//
// Note, that one can specify new file name for digits branch, and repeat digitization with
// another set of parameters.
