// Implementation version v0 of EMCAL Manager class 
// An object of this class does not produce hits nor digits
// It is the one to use if you do not want to produce outputs in TREEH or TREED
// This class places a Geometry of the EMCAL in the ALICE Detector as defined in AliEMCALGeometry.cxx                 
//*-- Author: Yves Schutz (SUBATECH)

// This Version of AliEMCALv0 reduces the number of volumes placed in XEN1 (the envelope) to less than five hundred
// The Envelope is Placed in Alice, And the Aluminium layer. Mini envelopes (XU) are then placed in XEN1.
// Each mini envelope contains 2 scintillator, and 2 lead layers, except the last one which contains just one scintillator layer.
// At the moment I cannot place the 36 and above layers in the mini envelopes so all layers are still placed in XEN1
