title: Order Solr/sunspot search results by geo location
body: <p>I'd like to be able to order my search results by score and location. Each user in the DB has lat/lot and I am currently indexing:</p>
  
  <pre><code>location :coordinates do
    Sunspot::Util::Coordinates.new latlon[0], latlon[1]      
  end
  </code></pre>
  
  <p>The model which I would performing the search against is also indexed in the same manner. Essentially what I am trying to achieve is that the results be ordered by score and then by location. So if I search for Walmart, I would like to see all Walmart's ordered by their geo proximity to my location.</p>
  
  <p>I remember reading something about solr's new geo-sort but not sure if it is out of alpha and/or if sunspot has implemented a wrapper. </p>
  
  <p>What would you recommend?</p>
