 * This interface is implemented by content type handlers that will be

 * called upon by libmime to process various attachments types. The primary

 * purpose of these handlers will be to represent the attached data in a

 * viewable HTML format that is useful for the user

 * Note: These will all register by their content type prefixed by the

 *       following:  mimecth:text/vcard

 *       libmime will then use the XPCOM Component Manager to

 *       locate the appropriate Content Type handler
