Searches this nodes children and their children to find a navigation node
with the matching key and type.

This method is recursive and searches children so until either a node is
found or there are no more nodes to search.

If you know that the node being searched for is a child of this node
then use the {@link global_navigation::get()} method instead.

Note: If you are trying to set the active node {@link navigation_node::override_active_url()}
may be of more use to you.

@param string|int $key The key of the node you wish to receive.
@param int $type One of navigation_node::TYPE_*
@return navigation_node|false
Searches this nodes children and their children to find a navigation node with the matching key and type .
