The layer to delete. This parameter cannot be null since you cannot delete the default root layer of the container.
true to also delete the layer children (objects and layers).
Use this method to delete a layer from the container as follows:
If deleteChildren is false, then only the layer is deleted and its children (objects and any child layer) will be added one level up in the container. For example, if this layer is a child of the root container, the layer children will be added to the container. If this layer has a parent layer, its children are added to the parent layer.
If deleteChildren is true, then the layer and its children (objects and any child layer) are completely removed from the container.
