/**
* Parses a mobile user agent string into it's basic constituent parts, the
* most important being vendor and model.
*
* One reason for doing this would be to use this information to lookup vendor-model
* specific device characteristics in a database. Of course you could use user agent
* profiles for this, but not all mobile phones have (valid) user agent profiles, especially
* the older types of mobile phones.
*
* Another reason would be to detect if the visiting client is a mobile handset. You could do
* it like this:
* <pre>
* require_once('MobileUserAgent.php');
* $mua = new MobileUserAgent();
* $is_client_mobile = $mua->success();
* </pre>
