Detailed Description

template<class TR>
struct TrajCandLess< TR >

Defines an ordering of Trajectories in terms of "goodness" The comparison is done in terms of total chi**2 plus a penalty for "lost" hits. This is OK for tracks of almost same number of hits, as in TrajectoryBuilder use, but is not applicable for tracks of different number of thits: the shortest track is likely to be considered "better".
