title: Detect compatible versions of Internet Explorer for dropzone.js
body: <p>Dropzone.js says that it <a href="http://www.dropzonejs.com/#compatibility" rel="nofollow">supports</a> Internet Explorer versions 10+. I'm not really worried about browsers other than Internet Explorer being too old.</p>
  
  <p>How should I detect whether the browser is compatible with dropzone? Should I detect it by its features (which is what some people say about browser compatibility), or by checking the version of the browser, and if so, how?</p>
  
  <p>(I'm using Rails, if that makes a difference)</p>
