title: Google calendar API and node js - "googleAuth is not a constructor" issue
body: <p>I'm trying to set up Google calendar API on Node, using the Node.js quick start that appear <a href="https://developers.google.com/google-apps/calendar/quickstart/nodejs" rel="noreferrer">here</a> </p>
  
  <p>After following all the first 3 steps and running my quickstart.js to check if it works (which i copied and pasted from the quickstart) , i get the following error:</p>
  
  <p>"TypeError: googlAuth is not a constructor"
  it refer to this line of code :</p>
  
  <pre><code>  var auth = new googleAuth();
  </code></pre>
  
  <p>googleAuth is declared like that: </p>
  
  <pre><code>var googleAuth = require('google-auth-library');
  </code></pre>
  
  <p>i couldnt find any solution online. </p>
  
  <p>the full code is on the link above on the third step.
  thanks in advance,
  Assaf.</p>
