virtual bool	on_enter_node (base_ptr b)
	called before a node b is processed, return, whether to skip this node. If the node is skipped, the on_leave_node callback is still called

virtual bool	on_leave_node (base_ptr b)
	called when a node b is left, return whether to terminate traversal

virtual bool	on_enter_children (group_ptr g)
	called before the children of a group node g are processed, return whether these should be skipped. If children are skipped, the on_leave_children callback is still called.

virtual bool	on_leave_children (group_ptr g)
	called when the children of a group node g have been left, return whether to terminate traversal

virtual bool	on_enter_parent (node_ptr n)
	called before the parent of a node n is processed, return whether this should be skipped. If the parent is skipped, the on_leave_parent callback is still called.

virtual bool	on_leave_parent (node_ptr n)
	called when the parent of a node n has been left, return whether to terminate traversal
