A MIME encoded message.
This is basically a collection of MIMEAttachment objects. This
class takes care of the ASCII encoding of the message as a whole,
including the segment boundary, etc... It does NOT
take care of any headers other than the Content-Type, which it
always identifies as "MULTIPART/MIXED".
This class can also be used to parse "file upload" information
out of HTML forms.
