Use marshmallow / flask-marshmallow

Right now we're using SQLAlchemy models to create JSON output (and interpret JSON inputs) for the endpoints. This means that the models are coupled to the endpoints. A better approach is to create a transformation layer between the models and the endpoints. Marshmallow is the ideal tool for this with Flask.
