New files. A tree model using a GNode structure to store it's info.

2000-06-08  Chris Toshok  <toshok@helixcode.com>

	* e-tree-gnode.c, e-tree-gnode.h: New files.  A tree model using a
	GNode structure to store it's info.

	* e-tree-model.c, e-tree-model.h: New files.  A proxy model
	sitting between a table model and the real tree model (of which
	ETreeGNode is an example).

	* e-cell-tree.c, e-cell-tree.h: New files.  A cell renderer
	capable of wrapping up a subcell and drawing the tree controls for
	expanding/collapsing trees.

	* tree-expanded.xpm, tree-unexpanded.xpm: New files.  the standard
	+ and - icons.

	* e-tree-example-1.c: New file, giving a (pretty poor :) example
	of using ETreeGNode.

	* Makefile.am: at the tree stuff to the build, and build
	tree-example-1.

	* .cvsignore: ignore tree-example-1.
