A heatmap.
You can access an existing heatmap 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 heatmap style layer and add it to the style using a method such as
`-[MGLStyle addLayer:]`.
### Example
```swift
