Website documentation

This pull request will merge all of the documentation currently hosted on the GitHub Pages website. This will make it a bit easier to avoid breaking changes while also make the doc development process more collaborative.

Unfortunately it might not be straightforward to preview the documentation html files, so this may have to happen locally for each developer.

TODO:

• General edits
• Add more references for theory and maybe use-cases
• Fill in the rest of the table

Supported data page

• General edits
• Add more detailed information(?)

SWOT example notebook

This is great!

Some of the places where I see some some work needed (I can assist/lead parts of this!):

• FluidSF Intro: Generalize to include broader utility of structure functions
• Getting Started: Adapt the example to use some real or physically-meaningful synthetic data (i.e., a field with a mean gradient or an oscillatory variation in one direction). This will be more interpretable/useful to a new user?
• Getting Started: Shift after "What are SFs" section for logical progression
• Getting Started: To make more interpretable, add plots of the fields (velocitity, advection) to make it clear what is going on
• What are SFs: Focus discussion on the SFs that can be calculated or are physically useful and/or calculable with the current package (longitudinal/transverse; advective; scalar-blended; second-, third- and higher-order)

I reran the example notebooks that calculated structure functions before the bug fix in #26.
