// Macros performing the full simulation chain 
// Use Case : 
//          root> .L Simulation.C++
//          root> sim(2, "GSD", "PHOS EMCAL") --> generates 2 events (Config.C)
//                                                and produces Digits and SDigits  
//                                                for PHOS and EMCAL 
//          root> sim(2, "GSDM", "PHOS EMCAL") --> same as before but before making Digits
//                                                 the 2 signal events are merged with one 
//                                                 background event in ./bgrd/galice.root
