#include <TransientTrackKinematicParticle.h>
Class representing KinematicParticle created fromTransientTrack. Uses specific KinematicState builders and propagators. Extends KinematicParticle class implementing its abstract methods and adding several new ones.

Constructor using KinematicState, Previous state of particle last constraint used and original TransientTrack, if any. All the pointers can be set to 0 if there's no such information available. Constructor should be use by specific factory only. Propagator for TransientTrack KinematicState is used.
