Separates Reading resource into two endpoints: One for retrieving a single Reading by specifying the id, and another for retrieving several readings by specifying a date range, a sensor, etc
Adds new way of testing that the every objects received in the response corresponts exactly to the json serialized objects retrieved by performing the same database query as the the call to the api performs on the server side
Adds more tests && adds docstrings for tests in order to make it possible for developers to understand the API specs from readings the tets (in my dreams...)
