Detailed Description

GFRaveVertex class.

A Vertex contains information about its position and covariance. The tracks the vertex is consisting of are stored in smoothedTracks_. These GFRaveTrackParameters contain the weight of the corresponding track in the vertex, smoothed track parameters and a pointer to the original unaltered genfit::Track.
