Before submitting a pull request, check these things:

• Code should compile (that includes the travis build)
• All warnings should be fixed or disabled with a pragma
• Test the code functionality (the code should produce the desired behavior on your machine)
• Apply autoformatting
• Make sure there are no conflicts between your branch and master
• Did you add new dependencies? Add them to the .travis.yml and announce them in slack.
• Did you add new ROS topics or nodes? Document them here.
• Does your code follow the style guide?
