// Description:
//      Data object carrying infomration about a fitted track
//      (residuals, chi2,...)
//      This class is meant to serve as a container which can be
//      used witht the ROOT TreeViewer to produce plots
//
// Environment:
//      Software developed for the PANDA Detector at FAIR.
