Overview

This PR creates a style guide which gives an overview of code style requirements such as conventions for naming files, cases to use for various entities, and much more. This PR also adds links to this file in README.md and CONTRIBUTING.md. The idea is that, if we have a codebase that is organized in a uniform way, it will be more more intuitive to work with.

Test Plan

I verified that the markdown rendered as expected and that code examples provided in the markdown were syntactically valid and functioned as expected. No code was added, so no other tests were necessary.

Follow ups

The style guide can continue to evolve with the team and the codebase, but for now it can be considered complete.
