title: Determine the lat lngs of markers within a polygon
body: <p>I have a google maps app which plots markers as it loads. One of the new requirment is to to add a Polygon overlay encompassing a selection of markers by the user. I was able to achieve that using the Geometry Controls of the <a href="http://code.google.com/p/gmaps-utility-library-dev/" rel="nofollow noreferrer">GMaps Utility Library</a></p>
  
  <p>Now, the next step is to form a group of the selected markers for which I would need to determine if the lat lngs of the markers falls within the lat lngs of the polygon? Is there a way to determine the lat lngs of a polygon and compute if the marker's lat lng is within its boundaries?</p>
