file: Adds the npm package for a published library to your workspace, and configures your default
  app project to use that library, in whatever way is specified by the library's schematic.
  For example, adding `@angular/pwa` configures your project for PWA support:
  ```bash
  ng add @angular/pwa
  ```
  
  The default app project is the value of `defaultProject` in `angular.json`.
