title: Removing polylines from google maps
body: <p>I'm using the DirectionsRenderer to display a path, though after I'm done with that I'd like remove the polyline and carry on with things. I don't seem to have control over markers and polylines created by this function.</p>
  
  <p>Does anyone know how to remove such polylines, if it's not possible, other suggestions?</p>
  
  <p>I now you can use the suppress property, though since I'm using the polylines in the first phase, this doesn't really solve anything. </p>
  
  <p>Severely frustrated..
  Cheers!</p>
