Detailed Description

A concrete TrajectoryCleaner that assumes all trajectories coming from the same seed and therefore incompatible The "best" trajectory of is kept, the others are invalidated. The goodness of a track is defined in terms of Chi^2, number of reconstructed hits, and number of lost hits. As it can be used during PatternReco there is the option to not consider hits from the common seed
