Detailed Description

Base class for 2-parameters segments measuring position and direction in X projection.

Implements the AbstractDetMeasurement part of the interface for 2D RecHits in terms of localPosition() and localPositionError() and Direction. This segment is measuring the position and the direction in just one projection, the "X". Typical use case is a segment reconstructed only in X projection. To be used as base class for all 2D positional-directional segments. The coordinate measured is assumend to be the local "x" and "dx/dz"

2D Segments for the muon barrel system. 2D means that this segment has information about position and direction in one projection (r-phi or r-theta/zeta).
