/**
 * Processes trades
 * 
 * This file should parse current trades and process those whose deadline is met.  Actual trade processing, however,
 * should be done in the Trade class, as admins may invoke it for singular trades.
 * 
 * This file should be run via cron.  I recommend several times daily (for better response, since it's not time-critical
 * for fairness like waivers) on Tues->Sat at 2AM, but you can pick.
 * 
 * that line would look like:
 * 
 * 0 2,8,14,20 * * 1-5 /path/to/php /path/to/processtrades.php
 * 
 * alternately, win32 servers can use pycron (http://www.kalab.com/freeware/pycron/pycron.htm)
 * and have a line like
 * 
 * 0 2,8,14,20 * * 1-5 "c:\path\to\php" "c:\path\to\processtrades.php"
 * 
 * Since you're not accessing this via the web, you should place it outside of your document root.
 * There are no permission checks; therefore, anyone could prematurely execute a waiver claim if the
 * file is public.  Security through obscurity is a poor substitute.
