// Macro for running Panda simulation  with Geant3  or Geant4 (M. Al-Turany)
// This macro is supposed to run the full simulation of the panda detector with the STT option
// to run the macro:
// root  sim_complete_stt.C  or in root session root>.x  sim_complete_stt.C
// to run with different options:(e.g more events, different momentum, Geant4)
// root  sim_complete_stt.C"(100, "TGeant4",2)"
