+// 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.
