Title: Adds a slugify filter extension

The slugify filter removes characters and space from string, making it url
safe

* Includes tests
* Adds doc stub

/Aside, I had some trouble getting the test suite to run.
Installed Twig to /vendor, but various files were not found within the package, such as TestCase.php

Is that something you have come across before?
