	WP-dTree - Creates a JS navigation tree for your blog archives	
	Copyright (C) 2007 Ulf Benjaminsson (email: ulf at ulfben.com)	
	Copyright (C) 2006 Christopher Hwang (email: chris@silpstream.com)	 
	
	This is a plugin created for Wordpress in order to generate JS navigation trees	for your archives. 
	It uses the (much modified) JS engine dTree that was created by Geir Landrö (http://www.destroydrop.com/javascripts/tree/).
	Christopher Hwang wrapped the wordpress APIs around it so that we can use it as a plugin. He handled all development of WP-dTree up to version 2.2 (~2007).	
	
	This plugin was updated by sydcode in August 2013.
	email: sydcode@gmail.com | profile: http://www.freelancer.com.au/u/sydcode.html
	- fixed sorting in archives widget (wp-dtree-arc.php)
	- added items to "Sort posts by" dropdown in categories widget (wp-dtree-cat-widget.php)
	- added items to "Sort posts by" dropdown in taxonomy widget (wp-dtree-tax-widget.php)
	- added support for "Advanced Post Types Order" plugin (wp-dtree-cat.php)
	- added hooks for clearing cache when order updated (wp-dtree.php)
