Contributing

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, but do not mess with the VERSION. If you want to have your own version, that is fine but bump the version in a commit by itself in another branch so I can ignore it when I pull.
• Send me a pull request.
