Detailed Description

An updator for the Muon system This class update a trajectory with a muon chamber measurement. In spite of the name, it is NOT an updator, but has one. A muon RecHit is a segment (for DT and CSC) or a "hit" (RPC). This updator is suitable both for FW and BW filtering. The difference between the two fitter are two: the granularity of the updating (i.e.: segment position or 1D rechit position), which can be set via parameter set, and the propagation direction which is embeded in the propagator set in the c'tor.
