// description: 
//       creates digits from sdigits for several detectors
//       stores sdigits in separate file (or in the source file
//       with sdigits). Stores gAlice object and copies TE to the
//       file with digits
//
// input:
//       TString fileNameSDigits ... input file with sdigits
//       TString fileNameDigits ... output file with digits
//       Int_t nEvents  ... how many events to process
//       Int_t ITS, TPC, ...   many flags for diff. detectors
//
// History:
//
// 04.04.02 - first version
