Split the API specific models out from the workflow models to help me keep this straight.
Added tests to help me understand the errors thrown the and resolution path when a workflow specification changes in the midst of a running workflow.
A workflow specification knows it's version number, which is generated by the version of the files that make it up.
A workflow specification version number is the primary file (the lead BPMN) followed by a consistency ordered version each extra file associated with the workflow. A change in any file modifies the specifications version.
Adding a new script that script tasks can use to add in data about the study.
Moving all the test workflow specifications out of the main load.
fixing a pile of tests so they can find workflow specs that are now moved into the test directory.
