Faster track reconstruction with background
Segment reconstruction in presence of background is very slow using the bestChi2
method. We need an alternative way to select the best segment without trying all possible combinations, e.g. road usage or Hough transform.
Incidentally this should make fixing issue #31 easier (if a segment has high chi2, take out the hit farthest from the segment and refit).
This should also come with adding a branch called e.g. hitCount
equal to the number of hits used to fit the track.
