Particle is consructed directly from its KinematicState, chi2 and related information.

If no previous provided, initial and currnt kinemtic states of the particle will match, othereise, initial state will be taken from previous particle.

Particle is constructed out of corresponding TransientTrack, mass_guess and sigma, chi2 and ndf.

KinematicState is then propagated to the given point
