Requires GMP library

I deployed a package that includes this class, only to have an almost immediate response from several users that the package wouldn't function on their systems - and gave no errors, it just wouldn't run.

After much trial-and-error, I discovered that the problem was that the PHP installations having trouble have no GMP!

This class relies heavily on the GMP functions, and won't function without them. So, if you're scratching your head - wondering why it works on one system and not another - check your PHP installations for GMP!

Thanks Michael,

Really saved a day. Those who are testing locally having XAMPP setup, simply un-comment line extension=php_gmp.dll in php.ini and restart APACHE.
