Create the track fitter function implementation.

The magnetic field is intentionally given by-value since the variant contains shared_ptr anyways.

Parameters

trackingGeometry
multipleScattering	correct for MCS (mainly for debugging)
energyLoss	correct for e-loss
reverseFilteringMomThreshold	at which threshold
freeToBoundCorrection	Correction for non-linearity effect during transform from free to bound
