dear collaborator,
as I said at the last collaboration meeting, I am finalizing the offline pattern recognition.

Presently there is a version of it in svn not complete yet.
Because of that, for every MC truth physical track 2 tracks
are reconstructed by the pattern recognition, essentially one clone of the other.
So please don't be alarmed, I am finishing that piece of code right now and I think that in 1 week or 2
that feature will be eliminated

dear collaborators,
please find in svn the new version of

tracking/PndTrkTracking2.cxx
tracking/PndTrkTracking2.h
trackitracking/PndTrkCTFindTrackInXY2.cxx

Now the problem of the double tracks was eliminated.
Please let me know if you have problems

Hi all,
I run the new code and compared the results of the standard analysis macro (psi(2S)-> J/psi pi+ pi-), in blue you can see the "old" (february) results and in "red" the new ones.
You can see a bit of increase in efficiency, resolution is consistent. I would say that this version of the tracking code can be used by the analysts and can be included in the release.
Later I will check cleanup.
