Determine the probability that for each CDC hit that it came from the track with the given trajectory.

This will calculate a probability for each CDC hit that it came from the track represented by the given DReference trajectory. The probability is based on the residual between the distance of closest approach of the trajectory to the wire and the drift time for time-based tracks and the distance to the wire for wire-based tracks.
