LogUse.php

<?php

Thanks

hello, you must make private __construct(){}, otherwise we can create an instance by new Log() and without using get->getLogger()

Your protected static function configureInstance() doesn't return anything, so this is wrong:

* @return Logger

Except this, thank you very much!

Useful, thanks!
