I've just committed an implementation of a function optimization 
(downhill simplex) in to TooN. It's useful if you can't easily compute 
derivatives.

Feel free to comment/modify it and change the interface. The optimizer 
works, but I consider it as "experimental" at the moment.

Also, is the right place for this tag or TooN? It definitely falls under 
"numerics", to I think TooN, but RANSAC is in tag (but IRLS is in TooN).

Finally, is it sensible to put it in a subdirectory, like I have?

Comments/ suggestions?
