Given input 2D hits, build out the lists of possible 3D hits

   The current strategy: ideally all 3D hits would be comprised of a triplet of 2D hits, one from each view
   However, we have concern that, in particular, the v-plane may have some inefficiency which we have to be
   be prepared to deal with. The idea, then, is to first make the association of hits in the U and W planes
   and then look for the match in the V plane. In the event we don't find the match in the V plane then we
   will evaluate the situation and in some instances keep the U-W pairs in order to keep efficiency high.
