title: OpenLayers get Lat, Lon from polygon vertices
body: <p>I am trying to get the boundary box using a square polygon in openlayers. I need to get the North, South, West, and East values from the box. Right now  I am using :</p>
  
  <pre><code>var topleft = vectors.features[0].geometry.getVertices()[0];
  </code></pre>
  
  <p>to get the top left vertex. However it returns a value like this:</p>
  
  <pre><code>POINT(-13393350.718762 4024321.5982824)
  </code></pre>
  
  <p>How can I get the lat and lon values from this returned point?</p>
