	Copyright (c) 2009 Andrei Pfeiffer [www.upsidedown.ro]
	Based on the script written by Alen Grakalic [http://cssglobe.com] [http://cssglobe.com/post/1695/easiest-tooltip-and-image-preview-using-jquery]
	
	ATTRIBUTES:
	- xOffset: 10 - sets the Left offset of the tooltip (it adds to the current position of the mouse). Increasing the value will move it to the right.
	- yOffset: 10 - sets the Top offset of the tooltip (it substracts from the current position of the mouse). Increasing the value will move it up.
	
	HISTORY:
	- v1.0 (january 2010)
		- stable version
		- only made a plug-in from the script provided by Alen Grakalic, that can be called for specific elements, with specific parameters
	
	USAGE:
	- this was created to display a tooltip when hovering links with the text taken from the title="" attribute
	
	- default:
		$(document).ready(function(){
			$("a.tooltip").tooltipLink();
		});
	
	- or, customizabile:
		$(document).ready(function(){
			$("a.tooltip").tooltipLink({
				xOffset: 20,
				xOffset: 15
			});
		});
