   This class represents one vertex on the Jet axis to be fitted by the 
   "JetFitter" algorithm and all vertices are stored in a vector inside 
   the VxJetCandidate class.
   
   It contains a vector of pointers to the tracks which belongs to the vertex:
   this tracks "belong" directly to the VxJetCandidate.
 
   Properties of the single VxVertexOnJetAxis class are:
   FitQuality (chi2 and ndf)
   Num_vertex (gives the vertex numbering scheme, used internally by JetFitter, 
               should not be needed by the user)
   CompatibilityToPrimaryVtx (gives the probability of that vertex to be compatible 
                              with the primary vertex)
