Fix formatting issue in the contributing section.

Hey @paulczar, this is a trivial contribution.

We are going to test drive Meez and I hope make some contributions. Even though this was a trivial fix, I wanted to run tests, but don't know how. I cannot find them in lib or bin. Please advise.

Thanks! Boyd

There aren't any tests as of yet; this is perhaps a challenge you could take up if you're looking to contribute :smile:

I like the irony of a tool for building testing frameworks not having any tests of its own ;)

I would definitely welcome PRs to implement testing, I should probably build out some roadmap items.
