   	===== Purpose =====
	Provide set/get cookie support for flash
	
	\\
	===== How to use it =====
		1. copy cookieLib.js to the same place as your .html file which references your .swf
		2. put this lines in your .html file :
		---------------------------------------------------------------------------
			<script src="cookieLib.js" type="text/javascript"></script>
		---------------------------------------------------------------------------
		3. SET A COOKIE FROM FLASH:
		
			import flash.external.*;
			ExternalInterface.call("fs_setCookie", "cookieName", "cookieValue", "EXPIRATION");
			
			(expiration can be: "never", or "session" or a "number" representing minutes)
			(default expiration is "never")
			(session expires when the browser is closed)
			(minutes= "60" for 1 hour, "1440" for 1 day, etc...) 
			
		4. RETRIEVE A COOKIE FROM FLAH:
		
			import flash.external.*;
			var cookievalue = ExternalInterface.call("fs_getCookie", "cookieName");
