// AliITSMultReconstructor - find clusters in the pixels (theta and
// The parameter AssociationChoice allows to control if two clusters
// in layer 2 can be associated to the same cluster in layer 1 or not.
//
+// Two methods return the number of traklets and the number of clusters
+// in the first SPD layer (GetNTracklets GetNSingleClusters)
+//
// -----------------------------------------------------------------
//
// NOTE: The cuts on phi and zeta depends on the interacting system (p-p
// or Pb-Pb). Please, check the file AliITSMultReconstructor.h and be
// sure that SetPhiWindow and SetZetaWindow are defined accordingly.
