-# TODO
-# - Add normalize_ that converts max-results into MaxResults

-# - Each 'resource' should be its own object accessible

-# - Methods can either execute immediately or return 
-#   RestRequest objects which can be batched. 
-#
-# - 'Body' parameter for non-GET requests 
-#
-# - 2.x and 3.x compatible

-# JS also has the idea of a TransportRequest and a Transport.
-# The Transport has a doRequest() method that takes a request
-# and a callback function.

-# Discovery doc notes
-# - Which parameters are optional vs mandatory
-# - Is pattern a regex?
-# - Inconsistent naming max-results vs userId
