// 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)
-
//*-- and : Sahal Yacoob (LBL / UCT)
-
-
// 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
