class AliPHOSGeometry: public AliPHOSGeoUtils

 Geometry class  for PHOS : singleton
 PHOS consists of the electromagnetic calorimeter (EMCA)
 and a charged particle veto either in the Subatech's version (PPSD)
 or in the IHEP's one (CPV).
 The EMCA/PPSD/CPV modules are parametrized so that any configuration
 can be easily implemented
 The title is used to identify the version of CPV used.
