Example notebook for qutip tensorflow.

[AGaliciaMartinez]

Example notebook for qutip-tensorflow showcasing how to optimize a unitary gate.

The notebook has been written to work with colab. A badge has been included but I have not been able to test it properly yet. I need to merge the notebook first for that.

I am not sure how well git diff will work with notebooks. Nevertheless, you can take a look at the notebook in my fork at the branch example_notebook.

@AGaliciaMartinez I tidied up the notebook by getting all imports at the top and dividing the example in sections. Also removed redefining things and adding some more explanations. Please have a look.

This is extremely cool btw to be able to use qutip and tensor flow together in this seamless manner. The data layer + qutip-TensorFlow makes me very excited about various possibilities @hodgestar @jakelishman

I look forward to adding some more examples and documentation.

Reviewing here (since I can't open the notebook in the review page):

• The QuTiP auto_tidyup removal has landed now (qutip/qutip#1615) so we can remove that note now.
• It would be good to re-run with Matplotlib 3.3 to avoid all the matplotlib 3.4 errors in the output (although we should probably fix those in QuTiP itself too).

Thank you for reviewing @quantshah and @hodgestar! I implemented the changes suggested and will merge once the checks finish.
