       adding support for differentiating between pair of probabilities with PV or without

   This class stores the information about the compatiblity of the vertices fitted 
   on the Jet Axis among themselves and with the Primary Vertex.
 
   This class essentially contains a map between the pairs of VxVertexOnJetAxis and 
   the probability (the key of the map) to form a common vertex under the constraint of having this common vertex 
   on the JetAxis. This helps to reject light-quark jet random lifetime tracks when applying the 
   JetFitter algorithm to B-Tagging. (refer to the new JetFitter algorithm for more details)
