/** \class DTChamberRecSegment2D
*
* A 2D segment for the DT system for Phi projection.
* It's an intermediate data class between the normal DTSLRecSegment2D class and
* the DTRecSegment4D. The difference wrt DTSLRecSegment2D is that the segments it
* represents is build with the two phi SL. So this segment DOES not belong to
* the SL (as DTSLRecSegment2D), but to the chamber (via a DTRecSegment4D).
* A DTRecSegment4D has one of these objects, and so can access the full
* information of the two projections.
