[Christian Hergert <chergert src gnome org>]

commit c2db3acf88185acb489c1a0a6930b611a80ab0bc
Author: Christian Hergert <christian hergert me>
Date:   Sun Jun 14 11:49:30 2015 -0700

    tree: style cleanup
    
     - Move types to gb-tree-types.h to avoid cyclic includes
     - Move public tree functions to bottom of file
     - Move node functions to gb-tree-node.h
     - Make gb_tree_get_path() private
