Class Description

                                                                          
 BrLocalTrackingModule is a class for general tracking.  Both TPC         
 tracking objects inherit from it and use its methods.                    
 April 28, 2000
 New classes are being written to deal with TPC tracking taht do not
 inherit form this class but rather BrTrackFinderBase and
 BrClusterFinderBase.
					                                    

 Constructor.

 Default constructor for user.
 The name and title should be set properly.

 Destructor
 delete the clones array always created in constructor

 Clear the temporary ClonesArray for intermediate data
 structures.

 Create the temporary ClonesArray for intermediate data
 structures.

 Find tracks marked in track candidate list as bad
 and compress the LocalTrack container

 Fill selector i.e. TObjArray with the hits that

 Create the different groups of tracks group. i.e. those localtracks
 that has overlapping hits. Tracks in a track group are deemed ghosttracks
 the ghost busting is done at a later stage when the DetectorTracks
 are filled.

 Method to add to the output node a table consiting of the prefered
 best local tracks. The objects in this table are BrDetectorTracks
 These objects are used in all higher level tracking code that combines
 and matches tracks between detectors.

FitLocalTPCTrack takes the input Local Track, extracts the combined hits that
make up this track and does a fit to get a chisqr
Input arguments:
BrLocalTrack *localtrack	: the local track to be fit
Output arguments:
Float_t *sol          : output parameters from the fit
Float_t *covar        : covar
Input tables:
 None
Output tables:
 None

 Mark a track (during construction of all tracks for deletion in the
 by setting its status value.
 Why is this a routine in the local tracking, and not a property of
 localtrack right away (12/19/99-fv)?
