title: Disable scrollify plugin when reaches breakpoint
body: <p>This is the script I want to disable when the browser reaches the Bootstrap breakpoint of 768px width:</p>
  
  <pre><code>$(function() {
    $.scrollify({
      /*section: "section",*/
      interstitialSection: "interstitialSection", 
      offset: 30,
    });
  });
  </code></pre>
  
  <p>Thanks in advance. </p>
