title: Create polygon from routeboxer boxes
body: <p>I am trying to create a polygon from the boxes i obtain from the routeboxer algorithm. I am new to GIS and was looking for some pointers. I am also looking at the JSTS library but I think it can only give me intersections. I couldn't find much documentation anywhere. </p>
  
  <p>Is there a way I can combine the boxes to form a polygon so a single <code>$within</code> query can do the trick. Thanks.</p>
