Detailed Description

The DTrackFitter class is a base class for different charged track fitting algorithms. It does not actually fit the track itself, but provides the interface and some common support features most algorthims will need to implement.

The reason this is needed (instead of just using the mechanism already built into JANA) is due to the nature of charged track fitting. Specifically, tracks are usually fit first to the wire positions and then to the drift times. The algorithm for both is (at least usually) the same. However, we want to separate the wire-based and time-based fitting into 2 distinct stages allowing easy access to the wire-based fits.

There were a few options on how to handle this within the JANA framework but it was decided passing DTrackFitter objects through the framework was the best way to address it. Sub-classes of DTrackFitter will implement the actual algorithms, but JANA will only see these objects as pointers to the DTrackFitter base class. Only one DTrackFitterXXX object will exist for each thread (i.e. each JEventLoop). As such, the state of that object will likely be overwritten many times in a single event and it's internal data never used by anything outside of the TRACKING package. Also, the factories that produce the DTrackFitterXXX objects will make them as persistent and will turn off the the WRITE_TO_OUTPUT bit by default.

Fit a DTrackCandidate using a given mass hypothesis.

This will perform a full wire-based and time-based fit using the given mass and starting from the given candidate. The given DReferenceTrajectory is used to swim the track numerous times during the various stages but will be left with the final time-based fit result. The JEventLoop given will be used to get the hits (CDC and FDC) and default DTrackHitSelector to use for the fit.
