body: <p>Does anyone have a concise and robust implementation of Google's <a href="http://code.google.com/apis/maps/documentation/utilities/polylinealgorithm.html" rel="noreferrer">Encoded Polyline Algorithm</a> in C#?</p>
  
  <p>I essentially want the implementation of this signature:</p>
  
  <pre><code>public string Encode(IEnumerable&lt;Point&gt; points);
  </code></pre>
