### Developing

    npm install & npm start & open http://localhost:9966/

You'll need a [Mapbox access token](https://www.mapbox.com/help/create-api-access-token/) stored in localstorage. Set it via

    localStorage.setItem('MapboxAccessToken', '<YOUR ACCESS TOKEN>');

### Testing

Tests require an MapboxAccessToken env variable to be set.

    export MapboxAccessToken=<YOUR ACCESS TOKEN> && npm test
