Analysis of air pollution levels before and after lockdown in Delhi, India

[Mukulikaa]

This is the barebones of the air quality analysis tutorial. I have added some explanations so that people will have at least a high-level idea of the tutorial. I am going to add explanations and some more descriptive statistics soon.

Closes gh-110.

Thanks @Mukulikaa! A few initial comments:

• Make sure you add your tutorial to the README and the applications.md file, so it's shown on the ToC for the rendered site.
• I like that this is a simple application, but that means it might be better suited for beginners. In that case, we need to break down the code and explanations about what we're doing a little more. In particular, it might be nice to highlight the NumPy methods and functions being used in the computations.
• This is a style issue, and you may very well disagree, but since we are using notebooks, I'd prefer if the comments were not made on the code, but as markdown text, whenever possible.
• It would be nice to add a few links to references for the Wilcoxon test and the t-test, at least.

Thanks, @melissawm! I'll include these in my next version.

The rendered tutorial is here. I have tried to include some explanations or links wherever suitable to make it more or else self-contained. Let me know if I should add more explanations or any other improvements!
