Class for measurements in wire detectors (Straw tubes and drift chambers) which can measure the coordinate along the wire.
This is not valid for any kind of plane orientation choice: to use it you MUST choose a plane described by u and v axes with v coincident with the wire (and u orthogonal to it, obviously). The hit will be described by 8 coordinates: w_x1, w_y1, w_z1, w_x2, w_y2, w_z2, rdrift, zreco where w_ji (with j = x, y, z and i = 1, 2) are the wire extremities coordinates; rdrift = distance from the wire (u coordinate in the plane) and zreco = coordinate along the wire (w2 -w1) (in the plane reference frame, v coordinate).

Hits with a small drift distance get a higher weight, whereas hits with big drift distances become weighted down. When these initial weights are used by the DAF, the smoothed track will be closer to the real trajectory than if both sides are weighted with 0.5 regardless of the drift distance. This helps a lot when resolving l/r ambiguities with the DAF. The idea is that for the first iteration of the DAF, the wire positions are taken. For small drift radii, the wire position does not bend the fit away from the trajectory, whereas the wire position for hits with large drift radii is further away from the trajectory and will therefore bias the fit if not weighted down.

Construct (virtual) detector plane (use state's AbsTrackRep). It's possible to make corrections to the plane here. The state should be defined somewhere near the measurement. For virtual planes, the state will be extrapolated to the POCA to point (SpacepointMeasurement) or line (WireMeasurement), and from this info the plane will be constructed.
