title: skrollr.js: Turn off or destroy skrollr at a given window width
body: <p>I'm using <a href="https://github.com/Prinzhorn/skrollr" rel="nofollow">skrollr.js</a> to animate a few things on a page. I'd like to only initialize skrollr when the window viewport width is larger than a particular size, and completely remove it or destroy it when I'm below that viewport width.</p>
  
  <p>For instance, when the browser window width is greater than 600px, I want skrollr to be initialized, but when the browser's window width is less than 600px, I want to turn off or destroy skrollr.</p>
