Hyper-model to API adapter tools

[catmando]

It would be nice to interact with hyper-model on the client, but have the data backed by some arbitrary API.

So you could declare the models, but also declare how the models got loaded from some API, and how they got persisted back to the API.

Obvious case is making it work graphQL.

Could be some ideas on how to do this in TrailBlazer
