+ *     Proxy Detector v0.1 with curl-de-sac customizations

+ *     Description:
+ *             This class can detect if a visitor uses a proxy server by scanning the
+ *             headers returned by the user client. When the user uses a proxy server,
+ *             most of the proxy servers alter the header. The header is returned to
+ *             PHP in the array $_SERVER.
