Expose GET operations on resources as well. This allows us to read

"partials". The pattern is demostrated in the unittest:

Resource.query returns a list of "keys" to resources, which are
partially defined. They have enough data to allow $get to fetch the
whole gamout. Then $get fetches all the details of the resource.
