//	Call this function at the bottom of any page to display the copyright date notice,
//	name of the copyright holder, contact email, name for the email and any base copyright
//	date for multi-year copyrights in the footer frame of G3. 
//
//	For Example:
//
//	<script type="text/javascript">
//      	document.write(CopyrightNotice(2006));
//	</script>
//
//	This will display the following:
//
//			Copyright © 2006-2008
//		         All Rights Reserved
//
//	which will be centered on the page.
//	
//	The email address will be a mailto protocol hyperlink applied to the text of
//	the first argument.
//
//	If the last argument for the base copyright data is omitted the Copyright line
//	will simply be "Copyright (c) " and the current four-digit year.
//
//	The Modified: line derives its data from the lastModified property of the document.
