is_callable documentation

I just submitted documentation for the is_callable function. I _think_ is correct, but someone who knows more about it than I might want to look it over. It should appear soon in the user notes at: http://www.php.net/manual/en/function.is-callable.php Rick Thanks to Andrei Zmievski and leon <at> leonatkinson.com for the information I found in the archives on the function.
