/**
 * PHP_Debug : A simple and fast way to debug your PHP code
 * 
 * The basic purpose of PHP_Debug is to provide assistance in debugging PHP
 * code, by 'debug' i don't mean 'step by step debug' but program trace,
 * variables display, process time, included files, queries executed, watch
 * variables... These informations are gathered through the script execution and
 * therefore are displayed at the end of the script (in a nice floating div or a
 * html table) so that it can be read and used at any moment. (especially
 * usefull during the development phase of a project or in production with a
 * secure key/ip)
 *
 * PHP version 5 only
