class AliEMCALEMCGeometry: public TNamed

 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_FIRSTYEAR - geometry for December 2009 to December 2010 run period
                     with four Super Modules

   Adding V1 (EMCAL_FIRSTYEARV1, EMCAL_COMPLETEV1) - geometry from December 2009 ;
                1. Fixed bug for positions of modules inside SM
                   (first module has tilt 0.75 degree);
                2. Added Al front plate (width 1 cm) and 2 paper sheets per sampling
                   layer (additional 0.2 mm)
                   The sizes have updated with last information from production
                   drawing (end of October 2010).
                3. COMPLETEV1 contains now only 10 SM for runs for year 2011
                4. COMPLETE12SMV1 contains 12 SM for runs from year 2012 and on
                5. COMPLETE12SMV1_DCAL contains 12 SM and 6 DCal SM
                6. COMPLETE12SMV1_DCAL_DEV contains 12 SM and 10 DCal SM
		  7. COMPLETE12SMV1_DCAL_8SM contains 12 SM and 6 DCal SM and 2 extentions

   EMCAL_WSUC (Wayne State test stand)
      = no definite equivalent in old notation, was only used by
          Aleksei, but kept for testing purposes

   etc.
