Add a new layer below labels

Using the second argument of addLayer, you can be more precise.

// This is the important part of this example: the addLayer
// method takes 2 arguments: the layer as an object, and a string
// representing another layer's name. if the other layer
// exists in the stylesheet already, the new layer will be positioned
// right before that layer in the stack, making it possible to put
// 'overlays' anywhere in the layer stack.
// Insert the layer beneath the first symbol layer.
