[Rivet] Releasing Rivet 2.0

[Andy Buckley]

Hi all,

Since earlier in the week, and particularly after a useful conversation
with Frank S on Friday and some YODA merge script & Cython hacking that
followed, I'm now feeling that the YODA and Rivet2 head versions are
good enough for our long-planned release.

That's assuming that the D0 W charge asymmetry issue that I mentioned
before (from the H++ vaidation suite) is not actually a problem, since
no-one responded about that.

Has anyone else tried the head configuration recently? Any problems? Any
good reasons *not* to release?

If there's no opposition, I'll make a release candidate tag and tarball
so I can do a final test on lxplus. David, could you try running your
validation scripts on the head one last time, just to make sure that
nothing is _crashing_? We've been through the output numbers
sufficiently -- I just want to get good coverage to make sure that none
of the technical stuff I did in the last 10 days broke systems other
than mine. Once we've got the all clear, I'll tag Rivet 2.0.0 and YODA
1.0.3 (or 1.1.0?) and we can *finally* get this thing out!

Cheers,
Andy
