Detailed Description

This is the original algorithm for building endcap muon track segments out of the rechit's in a CSCChamber. cf. CSCSegmentizerTC.
'SK' = 'Sasha Khanov' = Speed King

A CSCSegment is a RecSegment4D, and is built from CSCRecHit2D objects, each of which is a RecHit2DLocalPos.

This class is used by the CSCSegmentAlgorithm.
Alternative algorithms can be used for the segment building by writing classes like this, and then selecting which one is actually used via the CSCSegmentBuilder.

Ported to C++ and improved: Rick..nosp@m.Wilk.nosp@m.inson.nosp@m.@cer.nosp@m.n.ch
