// Geometry class for EMCAL : singleton
// EMCAL consists of layers of scintillator and lead
// Places the the Barrel Geometry of The EMCAL at Midrapidity
-// between 0 and 120 degrees of Phi and
+// between 80 and 180(or 190) degrees of Phi and
// -0.7 to 0.7 in eta
// Number of Modules and Layers may be controlled by
// the name of the instance defined
-// EMCALArch2x has more modules along both phi and eta
-// EMCALArchxa has less Layers in the Radial Direction
+// EMCAL geometry tree:
+// EMCAL -> superModule -> module -> tower(cell)
+// Indexes
+// absId -> nSupMod -> nModule -> (nIphi,nIeta)
