Jupyter Notebooks for Tutorials(USER GUIDE)

This issue is more of a suggestion.

A small issue that users reading documentation face is unavailability of jupyter notebooks for the tutorial docs User Guide. User constantly has to copy paste code from the documentation or .rst file which results in wastage of time.
Having executable notebooks for new users would help them save time and quickly move on to using xarray for their specific tasks.It would ease the learning process for new users which may somehow bring more contributors to xarray community.

Let's take example of pyviz, holoviews, pytorch.

00 Setup — PyViz 0.10.0 documentation

holoviews/examples/user_guide at master · pyviz/holoviews · GitHub

Chatbot Tutorial — PyTorch Tutorials 1.1.0.dev20190507 documentation

All of them provide option to download the tutorial in the form of .ipynb file either in the beginning or end of the notebook.

Start by reviewing the User Guide tutorial pages, especially data-structures.html, and compare the linked PyViz, HoloViews, and PyTorch notebook examples. Define which tutorials need executable notebooks and how users will download them; the work is done when the selected tutorials have usable, downloadable .ipynb files.
