/**
 * _GET is the equivalent to PHP's $_GET
 * An associative array of variables passed to the current script
 * via the HTTP GET method. This function is called onload.
 * This means that as soon as this file is included _GET will be available
 *
 * example:
 *   If the curent URL contains GET parameters e.g.
 *   myurl.htm?color1=red&color2=blue
 *   then _GET['color1'] will contain 'red'
 *   and  _GET['color2'] will contain 'blue'
