Significant commit to tracking code

[David Lawrence <davidl@jlab.org>]

Hi Folks,

    This is just a heads up that I just made a fairly significant commit 
to the tracking code in the repository. This is mostly a an 
organizational change but a few files were added and many files were 
modified. Also, I figured while I was at it, I would remove several 
files from the TRACKING directory that I believe to be no longer in use. 
Below is the commit log for those not on the auto-email list.

    So, if you do an update and things just won't compile or run 
anymore, please aim the flames at me.

Regards,
-David

Log:

This commit includes a medium-sized reorganization of some of the tracking code.
Included are the following:

- Added DTrackHitSelector class and associated factory classes to make
  the hit selection algorithm central and separate from the track fitting
  algorithms in the DTrackFitter classes.

- Added ChiSq() pure virtual method to DTrackFitter class. This allows 
  other classes to more easily calculate a chisq/Ndof in the same way
  the fitter does without actually invoking the fitter.

- Updated the LSLM fitter plugin to include a ChiSq method as described
  above. The routine only returns zeros at the moment and will need
  to be updated.

- Re-tooled the DTrackCandidate:THROWN, DTrack:THROWN, and
  DParticle:THROWN factories to all work almost exactly the same
  and use the DTrackHitSelector and DTrackFitter classes to get the
  hits an chisq/Ndof values in a consistent way. This allows one to
  easily insert the thrown values at any of the 3 tracking stages for
  testing of the later stages.

- Added chisq and Ndof fields to DTrackCandidate class

- Removed the following files which were old and apparently no longer
  used:
	libraries/TRACKING/DTrack_factory_ALT1.h
	libraries/TRACKING/DTrack_factory_ALT1.cc
	libraries/TRACKING/Dmctrk_hit.h
	libraries/TRACKING/Dtrk_hit.h
	libraries/TRACKING/DTrackHit_factory_MC.cc
	libraries/TRACKING/DTrackHit_factory_MC.h
	libraries/TRACKING/DSeed.h
	libraries/TRACKING/Dmctrk_hit.cc

- Updated acceptance_hists plugin to use DMCTrackHit rather than the
  deprecated DTrackHit objects
