mv {tests/,}phpunit.xml{,.dist}

running the tests is a bit difficult since you have to specify the `-c` parameter to reference `tests/phpunit.xml`. from the phpunit docs:

    If phpunit.xml or phpunit.xml.dist (in that order) exist in the current working directory and
    --configuration is not used, the configuration will be automatically read from that file.

with the patch, it would just be `composer install && phpunit` to get it up and running :)
