To use the function getDeltaPathToVtx() in org.jlab.clas.tracking.kalmanfilter.zReference.KFitter, finalStateVec needs to be set.
New HB tracking by AI applies KF package for propagation.
In dc_v1, the function getDeltaPathToVtx() is not called, so the bug is missed to be found when test of new HB tracking with RGA data.
In dc_v2, the function getDeltaPathToVtx() is called for fixing of path length issue.
