cleanup, change name to VertexMapValidator
add code for using MiniAOD AssociationMap from tracks to vertices - make default but keep old code
fix name, AssociationMap now working, however results quite different - study in progress
additional changes for debugging
oops, numberOfHits() throws out low-pt tracks, better to just check charge(). this improves the pf2pc match
get charge right, pf2pc is ok now, make pf2pc default behavior
code to make a very simple validation tree
