/**

 * Wave Framework <http://www.waveframework.com>

 * Log Reader

 *

 * This is a simple script that is used to read log files stored by WWW_Logger class. 

 * It loads a log file defined by specific timestamp formatted as Y-m-d-H. By default 

 * it displays information about all the requests that have happened in the current 

 * hour, but if GET variable 'log' is supplied in same timestamp format, then that 

 * log file data is returned instead.
