46d3de27f Merge pull request #267 from sartography/feature/dmn_collect_policy 2d5ca32d5 Support for the "COLLECT" hit policy. * DecisionTable constructor now expects a third argument (the HitPolicy) * DMNParser now checks for a hitPolicy attribute, but defaults ot "UNIQUE" as Camunda doesn't put another in there if Unique is selected. * DecisionTable deserializer will default to a hitPolicy of "UNIQUE" if not value is in the Json. git-subtree-dir: SpiffWorkflow git-subtree-split: 46d3de27ffbcaf60025f09d1cf04fcc7ee98658a
