Document Type: javascript include

Description:
	This is a global javascript include that should be included on EVERY page.
	It calls the correct standardized stylesheet for each browser and provides
	many useful methods/functions.
	
	If you are calling this file from a page in the root directory, then call 
	it like this:

		<script language="JavaScript" type="text/javascript" src="global/global.js"></script> 

	If you are calling the file from somewhere else, you must call the script using the relative path or
	absolute URL.  You must also specify the path variable before you call the script.  Example:

		<script language="JavaScript">path = "../";</script> 
		<script language="JavaScript" type="text/javascript" src="../global/global.js"></script> 

	OR

		<script language="JavaScript">path = "http://www.infotree.com/";</script> 
		<script language="JavaScript" type="text/javascript" src="http://www.infotree.com/global/global.js"></script>

	Note: you MUST have the final slash after the absolute URL in the path.

	For more information read: global_js_readme.txt
