What do fibers/future actually do?
<p>What does the line of code below do?</p>

<pre><code>Npm.require('fibers/future');
</code></pre>

<p>I looked online for examples and I came across a few like this:</p>

<pre><code>Future = Npm.require('fibers/future');
var accessToken = new Future();
</code></pre>

<p>What will <code>accessToken</code> variable be in this case?</p>
