    Hi All,
I updated BrModuleMatchTrack{h,cxx} by including a new diagnostic
histogram which plots number of good matched tracks per
1000 event versus the event number (in k). This is a very easy tool
to check which part of the run can be really counted as a "good" or
achieved data. E.g. we detected that T1 tripped at some point in
run # 7718 and 7722. The two attached plots, run7718.gif and run7722.gif
show how the loses (because of this trips) can be quantified by looking at
the hGoodTracksVsEvNo.

It can be also useful for people who are doing the data analysis to
find out which part of the run has to be skipped in order to
avoid a wrong normalization.

I added  hGoodTracksVsEvNo in BrModuleMatchTrack so, it is active for
any pair of tracking detectors used do to track matching.

Because of some other commitments of minor changes to dc related
code I updated the BRAT revision number - a new tag is BRAT-2.7.3.

Regards
Pawel.
