class AliCollisionNormalization: public TObject

                      Implementation of   Class AliCollisionNormalization

  This class is used to store the vertex ditributions in the data
  and in Monte Carlo, needed to compute the real number of
  collisions a given sample is corresponding to.
  The strategy matches what described in CERN-THESIS-2009-033 p 119.
