      This function reconciles vertices, PFParticles and slc, then
      defines the parent (j) - daughter (i) relationship and PDGCode. Here is a
      description of the conventions:
 
      V1 is the highest score 3D vertex in this tpcid so a neutrino PFParticle P1 is defined.
      V4 is a high-score vertex that has lower score than V1. It is declared to be a
      primary vertex because its score is higher than V5 and it is not associated with the
      neutrino interaction
      V6 was created to adhere to the convention that all PFParticles, in this case P9,
      be associated with a start vertex. There is no score for V6. P9 is it's own parent
      but is not a primary PFParticle.
 
      P1 - V1 - P2 - V2 - P4 - V3 - P5        V4 - P6                  V6 - P9

      P3                                 P7 - V5 - P8
 
      The PrimaryID in this table is the ID of the PFParticle that is attached to the
      primary vertex, which may or may not be a neutrino interaction vertex.
      The PrimaryID is returned by the PrimaryID function
