* File      :   tnefparser.php
* Project   :   Z-Push
* Descr     :   This is tnef implementation for z-push.
*               It is based on Zarafa's tnef implementation.
*               This class does only simple reading of a
*               tnef stream. Most importantly, we currently
*               only support properties within the message itself,
*               and do not support recipient tables and
*               attachment properties within the TNEF data.
*               This class will accept TNEF streams with data about
*               recipients and attachments, but the information
*               will be ignored.
