[Rivet] Cuts rewrite syntax feedback

[David Grellscheid]

Hi everyone,

I have continued with the cuts branch a bit, to see what it will look
like in analysis code. So far I have only replaced the use of eta
vectors in final state related projections. Before I continue, I would
like your feedback on the syntax.


Please clone

  ssh://login.hepforge.org//hepforge/hg/rivet/private/cut-combiners

and then

  hg up -r b22c0
  cd src/Analyses

Look at

  hg diff -r 4a7e .

and you'll see the changes.


Thanks,

  David
