// Geometry class  for EMCAL : singleton  
// EMCAL consists of layers of scintillator and lead
// with scintillator fiber arranged as "shish-kebab" skewers 
// Places the the Barrel Geometry of The EMCAL at Midrapidity
// between 80 and 180(or 190) degrees of Phi and
// -0.7 to 0.7 in eta 
//
//     EMCAL geometry tree:
//     EMCAL -> superModule -> module -> tower(cell)
//     Indexes
//     absId -> nSupMod     -> nModule -> (nIphi,nIeta)
//
//   Name choices: 
//   EMCAL_PDC06 (geometry used for PDC06 simulations, kept for backward compatibility)
//      = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG in old notation
//   EMCAL_COMPLETE (geometry for expected complete detector)
//      = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG scTh=0.176 pbTh=0.144
//          in old notation
//   EMCAL_WSUC (Wayne State test stand)
//      = no definite equivalent in old notation, was only used by
//          Aleksei, but kept for testing purposes
//
//   etc.
