Detailed Description

Class to describe a Segment reconstructed in the MuonSpectrometer.

A segment is a straight line approximation of the muon trajectory within a MS station. The segment carries a reference posiiton, and a direction. Further is provides information about the fit quality and the number of precision and trigger hits involved in the fit
