Added configurable parameters for nValidHits, nMissIn, nMissMid, maxRelTrkIsoDeltaRp3, relTrkIsoDeltaRSize

Added configurable parameters for nValidHits, nMissIn, nMissMid, and relTrkIsoDelaRp3
tracks do not store eta phi pt (candidate do)
so here you must first create local arrays
float eta[trackCollection.size()], phi[trackCollection.size()], pt[trackCollection.size()];
float ptcone[trackCollection.size()]
fill in one loop
and then proceed with the combinatorial.
you can loop from i+1 if you fill both ptcone[i] and ptcone[j]
when you arrive at j (unless selection occurred) the sum over [0,j-1] have been done in the previous iteration over i...
