title: Shapely: Polygon from String?
body: <p>I have saved string representations of some Shapely Polygons:</p>
  
  <pre><code>'POLYGON ((51.0 3.0, 51.3 3.61, 51.3 3.0, 51.0 3.0))'
  </code></pre>
  
  <p>Is there some fast way of directly converting it back to the Polygon type? Or do I need to manually parse the strings to create Polygon objects?</p>
