Detailed Description

Contains the complete track as a concatenation of partial tracks.

A QwTrack contains the complete description of the track as a concatenation of multiple partial tracks. Associated with the track is the kinematical information, for use in the final Q^2 determination.

Several vectors of QwPartialTracks are stored in the QwTrack object. This allows for combining different QwPartialTracks with each other, and selecting the optimal fit.
