+
+	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
