module Contentful
# An object representing an answer by the contentful service. It is later used
# to build a Resource, which is done by the ResourceBuilder.
#
# The Response parses the http response (as returned by the underlying http library) to
# a JSON object. Responses can be asked the following methods:
# - #raw (raw HTTP response by the HTTP library)
# - #object (the parsed JSON object)
# - #request (the request the response is refering to)
#
# It also sets a #status which can be one of:
# - :ok (seems to be a valid resource object)
# - :contentful_error (valid error object)
# - :not_contentful (valid json, but missing the contentful's sys property)
# - :unparsable_json (invalid json)
#
# Error Repsonses also contain a:
# - :error_message
