/*==================================================
* Very lightweight debugger
*
* Author: John Brennan
* http://www.janisb.com
*
* This is a nice debugger that works in both IE and Firefox using the firebug console or another browser window
* The console is only available to Firefox browsers with the firebug extension installed.
*
* Usage:
* DEBUG.debug('my message here');
* DEBUG.warn('my message here');
*
* just remember to include this file above where these statements are
*==================================================
