Detailed Description

Refitted state for kinematic parameters To be used in KinematicParticleVertxFitter only. Class caches the refitted state of the particle and provide access to its parameters in both parametrizations: Kinemaic and extended Perigee.

Several methods are done just to be consistent with present KalmanVertexFitter structure
