mods to support reading all reservation data

Russen - 

Take a look at this and let mw know what you think. Let's discuss it.
A more thorough test would be:

   client = ZcPoolingClient::LocationQuery.new
   expect(client).to receive(:get).
      and_yield(location_response.to_json, request = double, double('response', code: 200))

This type of test allows everything after RestClient to be exercised with a fixture JSON response. I like to have at least one of these per API wrapper that I write.
