Continuous Integration (CI)

The basic idea of CI is that whenever you push a commit, tests start running automatically on some server.
If the tests pass, you have a bit more confidence that the code that you pushed doesn't break other things in the codebase.
If they fail, then the CI has generated some work for you

In our case, a CI pipeline has been set up at https://git.cs.lth.se/robotlab/heron/heron-ci/
For now, the only thing it does is spin up a ROS noetic docker image to follow the instructions in the readme of https://git.cs.lth.se/robotlab/heron/heron_workspace_setup/-/tree/noetic
If it builds, the pipeline succeeds. Important to note is that it checks out some repositories at `noetic`, not `master`.
