title: How to get Spin.js spinner to delay before stopping?
body: <p>I have code like this</p>
  
  <pre><code> var opts = {
      lines: 11, // The number of lines to draw
      length: 28, // The length of each line
      width: 25, // The line thickness
      radius: 35, // The radius of the inner circle
      corners: 1, // Corner roundness (0..1)
      rotate: 0, // The rotation offset
      direction: 1, // 1: clockwise, -1: counterclockwise
      color: '#000', // #rgb or #rrggbb or array of colors
      speed: 1.3, // Rounds per second
      trail: 61, // Afterglow percentage
      shadow: false, // Whether to render a shadow
      hwaccel: false, // Whether to use hardware acceleration
      className: 'spinner', // The CSS class to assign to the spinner
      zIndex: 2e9, // The z-index (defaults to 2000000000)
      top: 'auto', // Top position relative to parent in px
      left: 'auto' // Left position relative to parent in px
  };
  </code></pre>
  
  <p>And then I call the spinner like this:</p>
  
  <pre><code>var target = document.getElementById('foo');
  var spinner = new Spinner(opts).spin(target);
  //do other stuff here
  spinner.stop();
  </code></pre>
  
  <p>But I want to delay the spinner for sometime before it stops. How to achieve this? Any help is appreciated.</p>
