• Code is tested and works locally (including with --lint flag)
• docs/README.md is updated with link to below
• docs/modulename.md is created
• Everything that can be represented with a plot instead of a table is a plot
  • here tables are better to check correlation
• Report sections have a description and help text (with self.add_section)
• There aren't any huge tables with > 6 columns (explain reasoning if so)
  • columns are closely related and easy to read, despite >6

• Module does not do any significant computational work

Please pull in upstream changes - this will hopefully help the CI tests. I can't do it for you sorry as this PR comes from an organisation fork rather than a personal account (and so I don't have permissions to push to your PR branch).

@jakobmatthes - thank you so much for the contribution, and sorry it took so long to review! I created a new PR with comments #2231 as I can't push directly into your fork, and I wanted to merge with the master branch. Feel free to continue pushing into the new PR if you are still up to working on the module :) It would be great to have it merged!
