Code looking good, thanks! Before I merge this, can you please do this:

1. git rebase -i HEAD~2
2. pick the first, squash the second
3. provide a single, good and concise commit message
4. git push origin --force (given that your remote is named 'origin')

This will help us to keep the git log clean by ensuring that we always merge full feature implementations and not commits like "fixing this..", "adding newline" etc.

It is called "squashing". There is a nice explaining of it in the symfony contribution docs: http://symfony.com/doc/current/cmf/contributing/commits.html

Thanks!

Merged, thanks!

I converted the simple test implementation to a unit test upon merge.
