ENH: Interactive notebooks from the website tutorials page

[nathanshammah]

On the tutorials page, the notebooks can be seen using nbviewer. The notebooks are hosted in qutip-notebooks Github directory and in R.J. Johansson directory.

There is now a button to start My Binder from these nbviewer notebooks, in the upper right (My Binder allows to run the notebooks live interactively from the cloud, without installing Python or the environment with dependencies).

It may be nice to add a links to:

• My Binder
• nbviewer (full directory)

in the tutorials page on the website. Right now, My Binder can be called from Github only. Also, a nbviewer link is opened for each notebook only.

The quantum mechanics lectures by Rob do not run, as the conda environment is not configured. One could:

• push an environment.yml file to that directory
  or
• clone the tutorials in the qutip-notebooks directory and add a link in the notebooks to Rob's folder. This way, each software update in the environment.yml file will affect also these files.

The https://hodgestar.github.io/try-qutip site I put together is another approach to solving this. I will try get it connected up.

I've opened qutip/qutip-tutorials#57 for implementing an index .ipynb that would be a convenient thing to link to in try-qutip, Binder or nbviewer.

And #170 to make try-qutip discoverable.
