//       creates digits from sdigits for TOF detector
//       stores sdigits in separate file (or in the source file
//       with sdigits). Stores gAlice object and copies TE to the
//       file with digits
//
// input:
//       char* fileNameSignal ... input file with sdigits
//       TString fileNameDigits ... output file with digits
//       Int_t nEvents  ... how many events to process
//
