Detailed Description

Listens to the updates in map layer registry and does changes in layer tree.

When connected to a layer tree, any layers added to the map layer registry will be also added to the layer tree. Similarly, map layers that are removed from registry will be removed from the layer tree.

If a layer is completely removed from the layer tree, it will be also removed from the map layer registry.
