	q_XML -- Quick XML  v0.1.0 
	by Paul Zirkle	1/10/04 
	keless@skyesurfer.net 
	------------------ 
the following class will help you quickly and  
easily save data in a pseudo (read: non-compliant)  
XML format, as well as read it back in.  
 
see example code at the bottom of this file 
 
TODO: 
 READING-- 
 * make sure CLOSE tags correspond to current Node 
 * make sure nextAttr() deals with attrs on either side of a sub-node
