Tests

After being merged, you should 

1. head to https://travis-ci.org/profile
1. enable the `SeeYouLaterElevator` repo 
1. head to https://github.com/DavidBruant/SeeYouLaterElevator/settings/hooks > Travis and click "Test hook"

It will then trigger a first run, which will fail. Merging #20 should make them passing again.
