2000-10-24  Chris Toshok  <toshok@helixcode.com>

	* e-tree-model.c: make ETreeModel opaque, and switch from using
	g_new0 and g_free for ETreePath's to using g_mem_chunk routines.
	(e_tree_model_node_remove): free the path's save_id.  *
	(e_tree_model_set_expanded_default): add method to add default
	expanded status for parent nodes.
	(etree_set_expanded_recurse): make this more efficient.
	e-tree-model.h: make ETreeModel opaque.  add prototype for
	e_tree_model_set_expanded_default.
