Handle a collapse request by marking all descendents of that node as

2002-03-08  Christopher James Lahey  <clahey@ximian.com>

	* e-tree-memory.c (etmm_node_request_collapse): Handle a collapse
	request by marking all descendents of that node as needing their
	children recomputed.

	* e-tree-model.c, e-tree-model.h
	(e_tree_model_node_request_collapse): Added this signal to request
	that the view of your tree collapse this node.

	* e-tree-selection-model.c (etsm_selected_count): Pass the root of
	the sorted model here instead of the root of the base model.

	* e-tree-table-adapter.c (etta_proxy_node_request_collapse):
	Handle a collapse request by collapsing the node in the tree.
