title: How to create direction arrows for my polylines in Google Maps (V3)?
body: <p>I have routes as Google Maps Polylines in my project (an example, <a href="http://rutasgdl.com/rutas/626-2" rel="noreferrer">http://rutasgdl.com/rutas/626-2</a> ) and I want to add direction arrows to the routes. I want something like this (sadly, it is for Google Maps V2) <a href="http://wtp2.appspot.com/ArrowLine.htm" rel="noreferrer">http://wtp2.appspot.com/ArrowLine.htm</a></p>
  
  <p>Can you point me in the right direction in order to achieve this? Regards.</p>
