Removing numPHP from sf.net

I have requested the removal of the project from sf.net, because the code here is a subset of the one I've written for PEAR (pear.php.net and cvs.php.net/cvs.php/pear) as part of a series of Math_* packages.

I do not have time to maintain 2 parallel code tracks. Which is why the code in PEAR is the more mature and complete.

Tnxs to sf.net for having hosted the project, and the people who sent feedback.
