	* e-table-item.c (eti_event): change things so we focus the cell
	and select the row, and also dispatch the event to that row/cell.
	This fixes the problem with the tree where you had to click twice
	to activate the tree controls.

	* Makefile.am (libetable_a_SOURCES): remove e-tree-gnode.* and add
	e-tree-simple.*
	(icons): add tree-expanded.xpm and tree-unexpanded.xpm

	* e-cell-tree.c (ect_enter_edit): defer to subcell's view.
	(ect_leave_edit): defer to subcell's view.
	(visible_depth_of_node): visual depth, taking into account that
	the root node of the model might not be displayed.
	(offset_of_node): return the offset used to shift the subcell
	over.
	(ect_draw): don't draw vertical lines if we're the leftmode node
	(a visual root node).  also, don't shift x2 by the subcell offset,
	so we get ellipses like we're supposed to.
	(ect_event): remove GDK_BUTTON_RELEASE from the list of events
	that we care about.

	* e-tree-example-1.c: lots of changes, a more dynamic UI so we can
	test tree model api stuff.

	* e-tree-gnode.c, e-tree-gnode.c: removed files, since their guts
	have been rolled into e-tree-model.c

	* e-tree-model.c, e-tree-model.h: substantially changed.  too much
	to really describe here.  this should really be considered the
	first revision of these files :)

	* e-tree-simple.c, e-tree-simple.h: analogous to e-table-simple, a
	subclass that allows the use of function pointers.
