/*! \class TrackSegment
* \brief Derived Katabatic::AutoSegment for the router.
*
* We create one TrackSegment per aligned Katabatic::AutoSegment set,
* the TrackSegment is associated to the canonical one of the set.
*
* To provide some speedup, the full extention of the aligned segment
* set is computed once and stored in the TrackSegment itself.
* The drawback beeing that whenever one segment from the aligned
* set has it's extention modified, the full extention must be
* recomputed.
