// Use `app.import` to add additional libraries to the generated
// output files.
//
// If you need to use different assets in different
// environments, specify an object as the first parameter. That
// object's keys should be the environment name and the values
// should be the asset to use in that environment.
//
// If the library that you are including contains AMD or ES6
// modules that you would like to import into your application
// please specify an object with the list of modules as keys
// along with the exports of each module as its value.
