title: Angular 2 CLI and Underscore
body: <p>I am trying to include "underscore": "^1.8.3" using the current Angular 2 CLI
  and I get this error Cannot find module 'underscore'.</p>
  
  <p>This is how I try to import it.
  import * as _ from 'underscore';</p>
  
  <p>I went online to look for a solution which there where many from last year by including it in the system-config.js and typings.json files. However I do not have these files in my project. I guess they are no longer provided by the current Angular 2 CLI.</p>
  
  <p>Is there a solution for importing underscore with the new Angular 2 CLI?</p>
