RooFormula an implementation of ROOT::v5::TFormula that interfaces it to RooAbsArg value objects.

It allows to use the value of a given list of RooAbsArg objects in the formula expression. Reference is done either by the RooAbsArgs name or by list ordinal postion ('@0,@1,...'). State information of RooAbsCategories can be accessed used the '::' operator, e.g. 'tagCat::Kaon' will resolve to the numerical value of the 'Kaon' state of the RooAbsCategory object named tagCat.
