Functions
bool	isGroup (QgsLayerTreeNode *node)
	Check whether the node is a valid group node.
bool	isLayer (QgsLayerTreeNode *node)
	Check whether the node is a valid layer node.
QgsLayerTreeGroup *	toGroup (QgsLayerTreeNode *node)
	Cast node to a group. No type checking is done - use isGroup() to find out whether this operation is legal.
QgsLayerTreeLayer *	toLayer (QgsLayerTreeNode *node)
	Cast node to a layer. No type checking is done - use isLayer() to find out whether this operation is legal.
