>	Debug.js
	Charles Chen (http://www.charliedigital.com/)

	A debugging console for writing messages.  A more convenient way to monitor running state than 
	using window.alert().

	Accompanying CSS:

		#debug_container {
			overflow-y: scroll;
			height:160px;
			background:#000;
			color:#ccc;
			font-size:9pt !important;
			font-family:ProFontWindows,lucida console,courier new;
			padding: 2px;
			word-wrap: break-word;
		}

		span.s { color: #6c6;}
		span.w { color: #fc0;}
		span.e { color: #f00;}
		span.g { }
		span.h { color: #ff6; }

	Suggested usage, in the general case, is to us position: absolute.  Works with both IE5.5+ and
	FireFox 1.5.

	toggleOnClass and toggleOffClass are not fully realized yet.
