The ``MultipartDecoder`` object parses the multipart payload of
    a bytestring into a tuple of ``Response``-like ``BodyPart`` objects.

The basic usage is::

import requests
        from requests_toolbelt import MultipartDecoder

response = request.get(url)
        decoder = MultipartDecoder.from_response(response)
        for part in decoder.parts:
            print(part.headers['content-type'])

If the multipart content is not from a response, basic usage is::

from requests_toolbelt import MultipartDecoder

decoder = MultipartDecoder(content, content_type)
        for part in decoder.parts:
            print(part.headers['content-type'])

For both these usages, there is an optional ``encoding`` parameter. This is
    a string, which is the name of the unicode codec to use (default is
    ``'utf-8'``).
