    - Add fraction split feature:
      In addition to the 'regular' parameter split

        'splitCat : param'

      allow the 'fraction' parameter split

        'splitCat : param[remainderState]'

      All specializations of param will be the same for both splits
      except for the one for the remainderState of splitCat, which
      will be a RooFormulaVar calculating '1-sum(param_split[i])',
      enforcing that the sum of all parameter specializations is always one.
