Hi Enrique, Sorry for being slow about this. I haven't forgotten about it, it's just that I've been swamped with other work. I haven't done anything in that direction so far, but I will definitely do so at the end of this week, most likely on Saturday/Sunday. If you want to, you can start with whatever you wanted to work on and let me know so that I don't do the same thing. Again, sorry for being slow right now, but I'll do my best to show some work in the next few days. Nick
