* Fixes#66: As a developer, I want to limit the audience
that sees new features, so that we can control
the message and positioning of our tool.
Implements simple feature flagging via URL parameters.
Provide "?flags=x,y,z" to enable flags x, y, and z.
* Fixing type to use Location instead of URL
* Updating README with info on how to use feature flags
Addresses #11 item "Linting/formatting (eg eslnt, prettier)":
* Adding eslint, prettier, and config targeting Google, typescript, and both nodejs and client builds
* Addressing linter-found issues
* Adding lint and lint:fix commands
* Adding documentation
* Renaming workflow and adding lint check
* Adding documentation about VSCode linting/formatting, ran formatting on a few files, set up exclude list for gatsby develop, setup build to fail on error
* Addresses issue #16 -
Add styles via sass and module imports
Adds typed scss imports via gatsby-plugin-sass.
Makes use of .d.scss file generated by gatsby-plugin-scss-typescript,
but avoids importing that directly while they work out issue in gatsby v3.
* adding vscode config for easier local debugging
