[Rivet] Branched release-2-0

[David Grellscheid]

Hi everyone,

I branched the release-2-0 branch in the Rivet repository. Please put 
any new analyses and bugfixes there, and not on 'default'!

To check the branch you're on, look at 'hg summ'. To switch, do

   hg up -r release-2-0

Unless you explicitly switch to another location with '-r', your 
operations will all stay on the branch.

The 'default' branch is now free again to merge in any completed 
development features which will belong in 2-1. Progress on release-2-0 
should also be pulled into 'default' from time to time.



In Mercurial the most tricky operation is to disentangle checkins that 
got onto the wrong branch. Please make extra sure your commits go to the 
right place!

See you,

   David
