Candidate for a requested pull request

[dd-olive]

I have added an unauthenticated outline of a flask_resful Resource with a post, which is close to the requested PR that you outlined in the code here.

https://github.com/digitaldebrief/sample_auth/blob/b371c0e5d4500f4e9fe7f61284184e5ee3fc7c11/sample_auth/ext/restapi/resources.py#L17

I'm happy to put this into a format that can be accepted into the flask-project-template, if you are interested. It would be a much bigger project to get flask_simplelogin to work with flask_restful Resource post requests, but I am working on doing SOMETHING with identity and permissions that is relatively general. Again, I'm happy to contribute upstream or maintain my own fork, as you desire.
