/** Abstract base class for vertex is being used by the CbmKF Kalman Filter 
 *
 * @author  S.Gorbunov
 * @version 0.0
 * @since   02.12.05
 * 
 * The class members describes to the CbmKF Kalman Filter routines 
 * how to get acces to data in a derived (or user) class.
 *
 * To be used by high-level utilites like StsTrackFitter
 *
 * Usage is similar to CbmKFTrackInterface class
 *
