- easier to use this branch as a stepping stone to add to one's own
  codebase
- also allows troubleshooting of issues with the current package
  without needing a build (that might accidentally differ slightly
  from the published version during development)

- delete code that isn't associated with the example from this branch
  - and make package "private" so it's not published

- GitHub Pages loads from index.html in root of repo
- also edit webpack-dev-server config to load from root too

- ha, right that's pretty important

- CodeSanbox currently only works with CRA for browser sandboxes

changes necessary for CRA (or makes CRA support simpler):
- mv example -> src, app.js -> index.js,
  styles.cssm -> styles.module.css, index.html -> public/
  - for some reason the container height didn't go to 100% anymore, so
    I had to change it to 100vh instead
- change id of 'container' to 'root'
- use CRA's mostly default public stuff
  - change short name, name, title to RCS Example
  - replace index.html with CRA's for simplicity
- replace scripts and add config to package.json
- remove webpack config
- gitignore build/ dir again and remove gh-pages bundle

(deps): install react-scripts, remove all other devDeps
