Settup data adapter

[jcblw]

This will enable us to swap out database structures and api endpoints with the a couple lines of code rather then rewriting, the calls in the routing.

I need some ideas on what kind of structure we would want with this. Looking at what we have now we are pretty much connecting to external apis, which I dont think will always be the case.

Could we start this by making an adapter to static json hosted somewhere? That way we could setup our binto-portal to test against this static data - served up by a staging-test-binto-api in the cloud.
