module RestClient
  # The response from RestClient on a raw request looks like a string, but is
  # actually one of these.  99% of the time you're making a rest call all you
  # care about is the body, but on the occasion you want to fetch the
  # headers you can:
  #
  #   RestClient.get('http://example.com').headers[:content_type]
  #
  # In addition, if you do not use the response as a string, you can access
  # a Tempfile object at res.file, which contains the path to the raw
  # downloaded request body.
