Review JOSE submission - Comments to Introduction section

[jwagemann]

• Adjust the Introduction of the tutorial more with the learning objectives described in the paper
• Differentiate sections clearer: e.g. introduce a section for audience, learning objectives, how to use this tutorial, etc.
• Also telling the story - at the moment, the image is introduced, but not explained at all. If you include the image, then also highlight some of the most important findings and integrate the challenges / difficulties associated with this type of research and the reason why one needs this tutorial.
