19// Geometry class for EMCAL : singleton
20//
21// -- Author: Magali Estienne (magali.estienne@subatech.in2p3.fr)
22
23//
24// Usage:
25// You can create the AliEMCALGeoUtils object independently from anything.
26// You have to use just the correct name of geometry. If name is empty string the
27// default name of geometry will be used.
28//
29// AliEMCALGeoUtils* geom = new AliEMCALGeoUtils("EMCAL_COMPLETE","EMCAL");
30// TGeoManager::Import("geometry.root");
31//
32// MC: If you work with MC data you have to get geometry the next way:
33// == =============================
34// !!!!!!!!! This part has to be modified
35// AliRunLoader *rl = AliRunLoader::GetRunLoader();
36// AliEMCALEMCGeometry *geom = dynamic_cast<AliEMCAL*>(rl->GetAliRun()->GetDetector("EMCAL"))->GetGeometry();
37// TGeoManager::Import("geometry.root");
