Remove feature.coordinates

[springmeyer]

We are currently outputting both feature.coordinates and feature.geometry.coordinates. The former is the result of layer.feature(i).loadGeometry(); which is a custom structure of x,y in tile coordinates. The latter is geojson coordinates. I think we should output only the latter by removing this line:

@@ -69,7 +78,6 @@ function readTile(args, buffer, callback) {
         var layer = tile.layers[layerID];
         for (var i = 0; i < layer.length; i++) {
             var feature = layer.feature(i).toGeoJSON(args.x, args.y, args.z);
-            feature.coordinates = layer.feature(i).loadGeometry();
             collection.features.push(feature);
         }
     });

/cc @jfirebaugh who might remember if there was a reason for feature.coordinates = layer.feature(i).loadGeometry();.

No reason that I'm aware of.
