Coding Standards website

[psimk]

Some of our tools, such as transition-component and muban have their docs in separate .md files that are then bundled into a github pages website using vupress, see:

• https://mediamonks.github.io/transition-component/
• https://mubanjs.github.io/muban/

I think we can do the same for these coding standards, as they will continue to grow, it will become more difficult to maintain everything in a single README.md (also merge conflicts aren't fun 🙃). Even Airbnb, who we are basing this guide off, have a website for their standards https://airbnb.io/javascript/.
