title: Use Filesaver js with angular2
body: <p>i have checked all the post i can find on the use of Filesaver JS with angular, but i still could not wrap my head around a soution.
  I added this  to the map section of my system.config.js</p>
  <pre><code> 'filesaver': 'node_modules/filesaver/src/Filesaver.js'
  </code></pre>
  <p>I added this to the packages section of the system.config.js</p>
  <pre><code>  'filesaver': {defaultExtension: 'js'}
  </code></pre>
  <p>I then imported it in my service.ts this way</p>
  <pre><code>import { saveAs } from 'filesaver';
  </code></pre>
  <p>Yet i get this error.</p>
