// jQuery FCKEditor Plugin
// By Diego A. - diego@fyneworks.com
// 10-Aug-2007 - Added setHTML method
// 12-Jan-2008 - v1.1 - plugin now follows the jquery philosophy of $(selector).plugin();
// 12-Jan-2008 - v1.1 - the new structure allows multiple FCk configurations on one page
/*
 USAGE:
		$('textarea').fck({ path:'/path/to/fck/editor/' }); // initialize FCK editor
	
	ADVANCED USAGE:
		$.fck.update(); // update value in textareas of each FCK editor instance
