README

PHP mathematical "Clamp" function. It clamps a variable between two numbers. Simple.

Usage:

    $value = clamp(
        $min,  // The minimum you will accept
        $max,  // The maximum you can take
        $value // The value you wish to clamp
    );

Why?

I got sick of writing what should be a core PHP function into a Util class, only to discover other people populating that util class with other nonsense that really shouldn't be in a Util class.
