Detailed Description

This class combines several user defined constraints (by expanding the vector d and the matrices D and E). Usage: Add each constraint to a std::vector<MultiTrackKinematicConstraint* >. This vector has to be used in the constructor: MultiTrackKinematicConstraint combiC = new CombinedKinematicConstraint(std::vector<MultiTrackKinematicConstraint >) The produced object can be used by KinematicConstrainedVertexFitter.fit()
