title: Can I access the geoNear functionality of mongo via the ruby driver?
body: <p>I'm retrieving results from mongo based on a geo query using the ruby driver.
  I'd like the results to be returned with their respective distances.
  That facility is available at the shell using geoNear command:</p>
  
  <pre><code>db.runCommand( { geoNear : "places", near : [50,50], num : 10 } );
  </code></pre>
  
  <p>How do I do this via the ruby API?</p>
