Added the following columns:
* date_created - so we know when the file was created
* renamed workflow_version to just "version", because everything has a version, this is the version of the request.
* workflow_hash - this is just a quick way to see what files and versions are associated with the request, it could be factored out.
* study - a quick relationship link to the study, so that this model is easier to use.
* workflow - ditto
* approval_files - these is a list from a new link table that links an approval to specific files and versions.
The RequestApproval is logically sound, but still needs some additional pieces in place to be callable from a BPMN workflow diagram.
Altered the file service to pick up on changes to files vs adding new files, so that versions are picked up correctly as
users modify their submission - adding new files or replacing existing ones. Deleting files worries me, and I will need to revisit this.
The damn base test keeps giving me a headache, so I made changes there to see if clearing and dropping the database each time won't allow the tests to pass more consistently.
Lots more tests around the file service to make sure it is versioning user uploaded files correctly.
The "Test Request Approval Script" tries to find to assure the correct behavior as this is likely to be called many times repeatedly and with little knowledge of the internal system. So it should just "do the right thing".
Improving the study_info script documentation to provide detailed examples of values returned based on arguments.
Making the tests a little more targetted and less subject to breaking through better mocks.
Allow all tests to pass even when ther protocol builder mock isn't running locally.
Removing the duplication of reference files in tests and static, as this seems silly to me at the moment.
Moving the primary process id from the workflow model to the file model, and assuring it is updated properly. This was causing a bug that would "lose" the workflow.
Required Documents is becoming complicated, so making this it's own script task, removing it from study_info.py
The file_service is now very aware of this irb_documents file, so it will always need to exist. We seed this file
during setup, but it can be overwritten by the configurator.
