Update setup.py
Create api.py

initial api concept, normally I would use my api resource discovery url builder, but in the spirit of keeping things generic we'll leave as an exercise for the integrator.

This provides : 
   - settings configured Authentication class
   - authorised and authenticated user only access to Feedback items.
   - user owned instance creation
   -
Update settings.py

include overridable setting attribute for specifying the Authentication Class to use.

Defaults to SessionAuthentication (cookies).
