title: Closest of a list of addresses from a location
body: <p>does anyone know how i can return a googlemap with pins for every location within a set radius. Don't necessarily need a specific distance from potential plotted route. I want the user to be able to specify their address (postcode) and a set distance (10,20,50 miles) and then i can show these results on a map. I have the list of postcodes, held in my database, do i need to generate something like a kml?</p>
  
  <p>Cheers
