// Private utility class used by IDTrackStat to do track and hit counting
// Since I'm likely to changes the interface as needed,  
// I would not recommend anyone to use this class outside of IDTrackStat
//
// to-do-list
//   o  remove TrackCollection argument to addEvent. Is this really needed for the truthmatching?
//   o  add DR cut to the fake track cut
