Temp Documentation Notes

• Leave yarn.lock file checked in but do NOT touch it. It is auto-generated.
• Cleaned up eslint. We don't need the comments inline, its easy to search eslint.org for them.
• Simplified the webpack.config.js. I still want to use the parts.js you've set up, however theres no need for the moment - so we'll revisit it at the end of this sprint of when we actually need to handle this.
• Renamed app to lib. The convention i'd like to follow is:
  • /lib => the code inside is a library / exported as a library (most prob is an npm published package)
  • /src => the code inside is the src for a particular application (web or mobile)
