title: Check if coordinates are inside a KML polygon
body: <p>I have a KML file which defines a region (or polygon). I would like to make a function that checks if a given coordinate is inside or outside that polygon.</p>
  
  <p>This is the KML if you want to take a look: <a href="http://pastebin.com/LGfn3L8H" rel="nofollow">http://pastebin.com/LGfn3L8H</a></p>
  
  <p>I don't want to show any map, I just want to return a boolean.</p>
