//NETJOHNHENRY HERE, WHY?-------------------------------------------------------------
//------------------------------------------------------------------------------------
/*
	
	On the 30/03/2009 Giuseppe says:
	I've added inside central/include/cssandscripts.asp the
	<script type="text/javascript" src="/central/script/netjohnhenry.js"></script> declaration
	for both English and German site. That requires to bake all sites before the javascript class 
	would be available to all sites which I haven't done due to time constraints.
	I've therefore included this class here so it's quickly available and I can carry on with debugging tracking problem.
	Note: As the content team bake the rocco sites this hardcoded include will become obsolete and no longer needed.
	
	Please check the date of this message and, at your own discretion, if you believe enough time has passed since NETJOHNHENRY.js file 
	was included in the cssandscripts.asp file and you believe content team has baked already ALL sites, 
	then please delete the NETJOHNHENRY class from this file.
	
	Note: As you clean up, there is a copy of this is inside the German and English central/script/main.js.
