    Browser class
    
    Identifies the user's Operating system, browser and version
    by parsing the HTTP_USER_AGENT string sent to the server
    
    Typical Usage:
    
        require_once($_SERVER['DOCUMENT_ROOT'].'/include/browser.php');
        $br = new Browser;
        echo "$br->Platform, $br->Name version $br->Version";
    
    For operating systems, it will correctly identify:
        Microsoft Windows
        MacIntosh
        Linux

    Anything not determined to be one of the above is considered to by Unix
    because most Unix based browsers seem to not report the operating system.
    The only known problem here is that, if a HTTP_USER_AGENT string does not
    contain the operating system, it will be identified as Unix. For unknown
    browsers, this may not be correct.
    
    For browsers, it should correctly identify all versions of:
        Amaya
        Galeon
        iCab
        Internet Explorer
            For AOL versions it will identify as Internet Explorer (AOL) and the version
            will be the AOL version instead of the IE version.
        Konqueror
        Lynx
        Mozilla
        Netscape Navigator/Communicator
        OmniWeb
        Opera
        Pocket Internet Explorer for handhelds
        Safari
        WebTV
