Detailed Description

Problem-level description of a single vertex candidate.

This holds everything a caller has to supply about one vertex before it can be fitted: the constraint to fit against, the position the seed finder proposed, and the tracks assigned to it. It deliberately contains no per-iteration scratch data, so it stays meaningful independently of any particular fitter.
