title: Gem countries select helper
body: <p>I am trying to use the gem <code>countries</code> from <code>hexorx</code>.  I really don't know how to bring that in the select helper. I tried to use the helper <code>country_select</code> like this </p>
  
  <pre><code>&lt;%= f.country_select :country, :required =&gt; true %&gt;
  </code></pre>
  
  <p>The GitHub location of gem is <a href="https://github.com/hexorx/countries" rel="nofollow">https://github.com/hexorx/countries</a>.  </p>
