Camunda DMN

Author executable DMN 1.3 decisions for Camunda 8.8+. A .dmn file holds one Decision Requirements Diagram with one or more decisions; each decision is either a decision table or a literal expression. A BPMN business rule task references a decision by ID and gets the result back as a process variable.
