Detailed Description

An Abstract base class for estimators, calculating the compatibility of a track and a vertex. For the actual compatibility measure (usually chi2) see concrete implementation.

Estimate methods: the void method is used only inside the vertex fitter. It updates the chi2 of the LinearizedTrack
contained in the Trk::VxTrackAtVertex with the compatibility estimate The float method returns directly the measure of compatibility between track and vertex. Methods of other types may be added on request.
