    A message object is defined as something that has a bunch of RFC 2822
    headers and a payload.  It may optionally have an envelope header
    (a.k.a. Unix-From or From_ header).  If the message is a container (i.e. a
    multipart or a message/rfc822), then the payload is a list of Message
    objects, otherwise it is a string.

    Message objects implement part of the `mapping' interface, which assumes
    there is exactly one occurrence of the header per message.  Some headers
    do in fact appear multiple times (e.g. Received) and for those headers,
    you must use the explicit API to set or get all the headers.  Not all of
    the mapping methods are implemented.

        Parameter keys are always compared case insensitively.  The return

        LANGUAGE can be None, in which case you should consider VALUE to be
        encoded in the us-ascii charset.  You can usually ignore LANGUAGE.

        Your application should be prepared to deal with 3-tuple return
        values, and can convert the parameter to a Unicode string like so:

        The returned string is always coerced to lower case.  If there is no
        Content-Type header, or if that header has no charset parameter,
        failobj is returned.

S(s�Return a list containing the charset(s) used in this message.

        The returned list of items describes the Content-Type headers'
        charset parameter for this message and all the subparts in its
        payload.

        Each item will either be a string (the value of the charset parameter
        in the Content-Type header of that part) or the value of the
        'failobj' parameter (defaults to None), if the part does not have a
        main MIME type of "text", or the charset is not defined.

        The list will contain one string for each part of the message, plus
        one for the container message (i.e. self), so that a non-multipart
        message will still return a list of length 1.
