Added a validate_workflow_specification endpoint that allows you to check if the workflow will execute from beginning to end using random data. Minor fixes to existing bpmns to allow them to pass. All scripts must include a "do_task_validate_only" that restricts external calls and database modifications, but performs as much logic as possible.
