Detailed Description

This algorithm is based on the Minimum Spanning Tree (ST) approach for building endcap muon track segments out of the rechit's in a CSCChamber.

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

This builds segments consisting of at least 3 hits. Segments can share a common rechit, but only one.
