@intrepid42 can this be approved as it is? is there also a PR to master?

[mseidel42]

@perrozzi Yes, this should be ok as it is. PowhegHooksBB4L.h is nearly unaltered from the Powheg/b_bbar_4l repository, just added the veto counter.

Will do the PR for master later.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_9_2_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar

[davidlange6]
