  // IE version detection - http://stackoverflow.com/questions/4169160/javascript-ie-detection-why-not-use-simple-conditional-comments
  // We need this as IE sometimes plays funny tricks with the contenteditable.
  // ----------------------------------------------------------
  // If you're not in IE (or IE version is less than 5) then:
  // ie === undefined
  // If you're in IE (>=5) then you can determine which version:
  // ie === 7; // IE7
  // Thus, to detect IE:
  // if (ie) {}
  // And to detect the version:
  // ie === 6 // IE6
  // ie > 7 // IE8, IE9, IE10 ...
  // ie < 9 // Anything less than IE9
  // ----------------------------------------------------------
