Subject: Added this simple accessor function.

2002-01-31  Christopher James Lahey  <clahey@ximian.com>

	* e-tree-selection-model.c, e-tree-selection-model.h
	(e_tree_selection_model_get_cursor): Added this simple accessor
	function.

	* e-tree.c, e-tree.h (e_tree_find_next): Searches from the cursor
	given the search parameters and moves the cursor if it ever
	matches.
