Travis & Scrutinizer

I've added a full test suite, using codeception, travis, and scrutinizer.
run composer install (or php composer.phar install, if you dont have it globally installed).
run tests with: 
vendor/bin/codecept run unit --coverage-html
code coverage report available in tests/_output/index.html
I removed the old unit tests and put them in codeception compatible tests, although i have them commented out for now as i havent actually looked into your code properly yet.
I added a first unit test to get things started.
