Hi, Ali:<br /><br />I'm actually working on it right now. It's coming along, but I would like to spend as much time on it as possible. If you need the document by a certain time, I can send you what I have and finish it this evening. Just let me know. As of now, I have about a quarter finished and I've tracked down some references.<br /><br />Best wishes - George<br /><br /><br />
