title: append globals to consuming applications .jshint file
body: <p>I am writing an addon that wraps a third party library that uses globals and exporting them as es6 modules <code>export default someGlobal</code>.  The problem is that the consuming applications still sees the globals and complain during unit tests.</p>
  
  <ol>
  <li><p>Is there a way I can insert these globals into the consuming applications .jshint file via a blurprint?</p></li>
  <li><p>Is there a better way of exporting globals to es6 modules without actually modifying the third party code?</p></li>
  </ol>
