Detailed Description
This is the helix track class, which inherits from KalTrackingTemplate and TKalTrack.
Kalman filter algorithm comes from TKalTrack which is a class in KalTest package.

Use the current track state of the containerTrack to extrapolate into the next layer.
The distance can be positive or negative, depending if we move inwards or outwards, or 0 to get another intersection on the same layer.
Implements marlintpc::KalTrackingTemplate< TKalTrack >.

Create a track candidate by making a KalHit from the ModuleRowHit and creating a TrackSite from it.
Afterwards it copies the _kalTrack of this class and adds and filters with the new site. It also hands over the ownership of the new track, so don't forget to delete it. Attention: The new track is not the owner of the sites, as they belong to the original _kalTrack, except for the newly deleted site. Before deleting the candidate do not forget to delete the last added site on the track!
If the add and filter fails you get a 0-pointer;Search track starting from hit

Fill the track state (incl.
cov matrix) at the beginning (4th hit) of the track into the given LCIO track. Smoothes back to the 4th hit and returns that state.
