[Rivet] ATLAS ttbar+jets analysis

[Alexander Grohsjean]

Dear all,

I was prodividing the tools that we changed in a tar bal with just the 
modified/added files.
I summarized quickly the changes in a README in the main path.
So I must admit that I am not sure what is missing here. Diff should be 
very easy to run and to
see the changes providing this?

Changing names "FromElecroweakDecay" is perfectly fine with us, these were
just historically.
I started developing in 2.1.0, then updated to 2.1.1 at some point but
didn't switch to 2.1.2 as this happened after my validation. Should I 
now run it
in 2.1.2?

For validation, I attached the same distributions that we have in the 
paper (blue and red with ct10).
Should I provide the log-files from object by object comparisons?
These are the internal notes:
Jet multiplicity supporting note
https://cds.cern.ch/record/1532076
Jet pT supporting note
https://cds.cern.ch/record/1545583

Cheers, Alexander.
