/*
GetBrowserOSVersion()
written by Matt Pressnall 12/09/04

What does it do?
Get's the browser name, version, and OS for a client computer.  Replaces the older "getOSBrowserVersion" that doesn't correctly ID the version because browsers changed the way they represented version info

How do I use it?
<script src="/js/standardFunctionality/GetBrowserOSVersion.js"></script>
<SCRIPT LANGUAGE="JavaScript">
GetBrowserOSVersion();
</SCRIPT>
In global JS variables you will have access to:
browser - can return "Microsoft Internet Explorer", "Netscape", "Opera", etc...
version - can return "4","5", etc...
os      - can return "win" or "mac"
