Detailed Description

Builds the doublet graph of the GBTS workflow.

Turns a finalized GbtsNodeStorage into a graph whose edges are doublets and whose links are the doublet pairs that a triplet cut accepted. GraphBasedTrackSeeder follows the best fitted path along those links from every edge to produce seeds.

The phi binning is the node storage's, so the sliding windows and the indexing they slide over cannot disagree.
