A WorkflowInstance is an instantiation of the abstract description of a Workflow provided by the {@link Workflow} class. WorkflowInstances havestatus, and in general are data structures intended to be used as a means for monitoring the status of an executing {@link Workflow}.

                    Workflow wDesc = repo.getWorkflowById(wInst.getWorkflow()
