Detailed Description

This is the common class for 3D segments used in the muon spectrometer.

The Surface type for MuonSegments is restricted to be a PlaneSurface. The parameters of the MuonSegment are:

the Trk::LocalPosition of the segment in the surface reference frame
the Trk::LocalDirection of the segment which consistes of the angles \( \theta_{xz} \) and \(\theta_{yz}\).

The MuonSegment stores a list of Trk::MeasurementBase objects allowing it to contain measurements from all detector types in the muon spectrometer.
