/**
 * This script collects information on visitors, based
 * on their client session. It finds out which page they
 * were on when they go there, and by virtue of sending
 * that information to the logger, their IP. This is
 * information that you're sending already, anyway, but
 * I want you to know that this is what's going on.
 *
 * Which is why this script is not obfuscated. It simply
 * grabs your document.referrer value, which (unless Do
 * Not Track is enabled) will contain the location of
 * the page you were on before you clicked a link to this
 * page, and GETs that to my logger. That GET operation
 * comes from your computer, so will have your IP as part
 * of the HTTP headers.
 *
 * And that's all I really care about, because I want to
 * know how many people visit this page, and roughly where
 * they're from (gasp! IPs can be turned into rough
 * geographical location O_O).
 *
 * If you want to know what logger.php looks like, hit up
 * github. It's in referrer/logger.php
