@behrica, this is great.

A few little questions:

• In the do-generate-tests function, should we maybe simply generate the book so that all chapters of the book are handled?
  • or, alternatively, run over all the namespaces defined in the book's chapters.edn?
• Was 'notebooks/plonine.clj` added by mistake?
• Maybe use the most up-to-date version of Clay in deps.edn?

I loop now over all notebooks. If they have no tests, nothing will be generated.
