\subsection{Detailed Description}
A functor to return the quality of a track. 

For tracks with 4 hits or more the chi2prob is mapped to$\ast$ 0.\-5-\/1, with p' = p/2 + 0.\-5. Tracks with 3 hits get the chi2prob mapped to 0-\/0.\-5 by p' = p/2. This way short 3-\/hit-\/tracks rank lower than 4-\/hit tracks.
