title: Snap.SVG how to stop all animations
body: <p>I want to find a way of stopping all animations on all rectangle elements within the SVG when a certain element is clicked. 
  I'm trying to use something like this:</p>
  
  <pre><code>svg.select("rect").stop();
  </code></pre>
  
  <p>but I can't get that to work</p>
