5 . expect an api instead of a config (and api.config is set)
8 . cannot access their driver from self, but from the context (api is passed to methods)
11 . use api.dbsession() whenever possible
12 . it's fair to have importers and sfaadmin use the global session (there won't be instances of api in their case)
13 . there is one or 2 exceptions where dbsession is retrieved from an sqlalchemy object but this is deemed poor practice, please DO NOT do this as far as possible
