Add further examples

[bkmgit]

It may be helpful to add/link further examples from

• https://github.com/JeanKossaifi/caltech-tutorial
• https://github.com/JeanKossaifi/tensorly-notebooks
• https://github.com/JeanKossaifi/caltech-tutorial-19
• https://github.com/tensorly/Proceedings_IEEE_companion_notebooks

Choosing one set of examples for the documentation would make learning and maintenance upgrades easier

I agree, adding more examples is on my todo list! Feel free to have a crack at it though! :)
