Install all peer dependencies

• npm: npx install-peerdeps --dev eslint-config-tnez
• yarn: npx install-peerdeps --dev -Y eslint-config-tnez

Add .eslintrc:

{
  "extends": ["tnez"]
}

(Optionally ) Add .prettierrc that matches config in order to play nicely with editor plugins:

{
  "semi": false,
  "singleQuote": true,
  "trailingComma": "all"
}
