/**
* Layer tree node points to a map layer.
*
* When using with existing QgsMapLayer instance, it is expected that the layer
* has been registered in QgsMapLayerRegistry earlier.
*
* The node can exist also without a valid instance of a layer (just ID). That
* means the referenced layer does not need to be loaded in order to use it
* in layer tree. In such case, the node will start listening to map layer
* registry updates in expectation that the layer (identified by its ID) will
* be loaded later.
*
* A map layer is supposed to be present in one layer tree just once. It is
* however possible that temporarily a layer exists in one tree more than just
* once, e.g. while reordering items with drag and drop.
*
* @note added in 2.4
