Detailed Description

Algorith to build TrajectorySeed for muon standalone reconstruction. The segments are sorted out to make a protoTrack (vector of matching segments in different stations a.k.a. layers), for DT+overlap and CSC regions, in that order. The protoTrack is then passed to the seed creator to create CSC, overlap and/or DT seeds.
