	To use the navigationFormatter function, you must have a function that
	accepts two paramaters, and returns a string of HTML text.
	
	index = integer index (1 based);
	panel = jQuery wrapped LI item this tab references
	@return = Must return a string of HTML/Text
	
	navigationFormatter: function(index, panel){
		return index + " Panel"; // This would have each tab with the text 'X Panel' where X = index
	}
