(Unicode C++) Parsing a Multipart/Digest Email

This example demonstrates how to parse a multipart/digest email. An email parsed by this sample could have a MIME structure as follows:

multipart/mixed
    text/plain
    text/plain
    multipart/digest
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
        message/rfc822
    text/plain
