* Comments
* It is not perfect, but at least gives some idea which PHP files some page uses
*
* Include this script on the page you want to sniff for PHP file usage and
* use the page normally, as in go through page's controls of which you think
* make ajax calls. To view sniffer results type "sniffed_php_dependencies"
