Babel Config

Factory functions for creating preset Babel configurations. Primarily used in
unison with the Lumos CLI.

Extending config

Update package.json:

``json
{
"lumos": {
"eslint": {
"plugins": ["styled-components"]
}
}
}
`

Create file in configs folder:

configs/babel.js

`js
modules.exports = {
plugins: ['styled-components'],
};
`
