title: Update Google Map automatically when Google spreadsheet is updated?
body: <p>I'm using <a href="https://mapsengine.google.com/map/?" rel="noreferrer">Google Maps Engine Lite</a> and placing markers on the map from a Google spreadsheet. At the moment I'm importing these manually into a layer.</p>
  
  <p>Is there a way to automatically update the pins when the spreadsheet is updated?</p>
  
  <p>There very little out there on this or is it because this needs to be done via the API with a coded solution?</p>
