   An `MGLFillStyleLayer` is a style layer that renders one or more filled (and
   optionally stroked) polygons on the map.
   
   Use a fill style layer to configure the visual appearance of polygon or
   multipolygon features. These features can come from vector tiles loaded by an
   `MGLVectorTileSource` object, or they can be `MGLPolygon`, `MGLPolygonFeature`,
   `MGLMultiPolygon`, or `MGLMultiPolygonFeature` instances in an `MGLShapeSource`
   or `MGLComputedShapeSource` object.
  
   You can access an existing fill style layer using the
   `-[MGLStyle layerWithIdentifier:]` method if you know its identifier;
   otherwise, find it using the `MGLStyle.layers` property. You can also create a
   new fill style layer and add it to the style using a method such as
   `-[MGLStyle addLayer:]`.
  
   ### Example
  
   ```swift
   let layer = MGLFillStyleLayer(identifier: "parks", source: parks)
   layer.sourceLayerIdentifier = "parks"
   layer.fillColor = NSExpression(forConstantValue: UIColor.green)
   layer.predicate = NSPredicate(format: "type == %@", "national-park")
   mapView.style?.addLayer(layer)
   ```
