Detailed Description
template<class ContainerT>
class marlintpc::KalTrackingTemplate< ContainerT >
This is a base KalDet tracking class.
It provides common methods for tracking.
It is templated for a container which contain the track state. For compatilibity with with TKalTrack it has to imolement SetOwner(), Clear() and Last(). Last may just return a null pointer.

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;Get the deltaChi2 from the track candidate
Implemented in marlintpc::KalTrackingHelix, and marlintpc::KalTrackingStraight.

Add a new site to track and update track parameters.
The track is given as an argument so it can also be used for track candidates and not only for the class-wide variable _kalTrack.
Only to be called after the track has been initalised with a first track state.
Implemented in marlintpc::KalTrackingStraight, and marlintpc::KalTrackingHelix.

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.
Implemented in marlintpc::KalTrackingHelix, and marlintpc::KalTrackingStraight.
