Add a helper method to split a systematic variation between regions
As discussed in https://gitlab.cern.ch/cp3-cms/bamboo/issues/55 .
Tests done: added
splitVariation(tree._Jet, "jer", {"backward" : lambda j : j.eta < 0., "forward" : lambda j : j.eta > 0.}, nomName="nominal")
after the configureJets
call in the HH module, the generated code looks all right.
More ideas/suggestions/tests welcome!
