I fixed issues with the sidebar for the tutorial as well as added two
new sections for the tutorials: one about how to invert the mapping of
the trainer, and one which extends the notes about custom coupling cells
and which shows how to use them in a trainer.
Feel free to suggest me also additional sections for the tutorial if something comes to your mind; I would add them then also in this PR.
