title: Translate array of countries from Countries Gem in Rails
body: <p>I have an array of countries:</p>
  
  <p><code>Country.all.sort{ |c1,c2| c1[0] &lt;=&gt; c2[0] }</code></p>
  
  <p>How would I incorporate the <code>translations</code> method of the <a href="https://github.com/hexorx/countries#country-info" rel="nofollow">Countries Gem</a>? So if pass in a locale, I could get back an array of translated countries?</p>
