public void addNode(GTreeNode node) {
		Swing.runNow(() -> doAddNode(node));
	}
Adds the given node as a child to this node. Note: this method may be inefficient so if you
have many nodes to add, you should use either {@link #addNodes(List)} or
{@link #setChildren(List)}

@param node the node to add as a child
