Not completely sorry. I was about to send you some comments a couple of weeks ago then had to leave urgently and forgot about it, then started rewriting your code and didn't finish :-) I'll give you some more feedback asap, sorry about that. It's getting there but there's a couple of things I'd like to see done a bit differently.
