Changed these to match the new ETable system.

2000-10-11  Christopher James Lahey  <clahey@helixcode.com>

	* tests/test-tree-1.c, tests/test-tree-2.c, tests/test-tree-3.c:
	Changed these to match the new ETable system.

	* gal/Makefile.am: Added e-table-column-specification.lo,
	e-table-extras.lo, e-table-specification.lo, and e-table-state.lo.

From gal/e-table/ChangeLog:

2000-10-11  Christopher James Lahey  <clahey@helixcode.com>

	* Makefile.am: Added e-table-column-specification.c,
	e-table-column-specification.h, e-table-extras.c,
	e-table-extras.h, e-table-specification.c,
	e-table-specification.h, e-table-state.c, and e-table-state.h.
	Removed some duplicated .h files.

	* e-cell-tree.c: Ref, sink, and unref the subcell instead of destroying
	it when done.

	* e-table-column-specification.c, e-table-column-specification.h:
	New class which describes a column without having a table get
	instantiated.

	* e-table-config.c: Changed get_specification to get_state to get
	this to compile.

	* e-table-defines.h, e-table-item.h: Moved the definition of
	ETableCursorMode from e-table-item.h to e-table-defines.h.

	* e-table-extras.c, e-table-extras.h: New class which acts as a
	set of 3 hash tables.  All from char * and to alternately, ECells,
	GCompareFuncs, and GdkPxibufs.

	* e-table-scrolled.c, e-table-scrolled.h: Changed this to match
	the new ETable function declarations.

	* e-table-sort-info.c, e-table-sort-info.h: Added functions for
	saving to and loading from xml.

	* e-table-specification.c, e-table-specification.h: New class
	which describes a table without having to instantiate it.

	* e-table-state.c, e-table-state.h: New class which describes the
	state of a table without having to instantiate the table.

	* e-table.c, e-table.h: Changed this to accept both a state and a
	specification instead of just a specification.  You then save only
	the state.  The specification stays exactly the same.  Also, you
	no longer need to pass in an ETableHeader.  Most of the
	information contained in the ETableHeader are in the
	specification.  However you may need to translate some of the
	strings in the specification to objects.  If you need anything
	other than the builtin choices, you need to create an ETableExtras
	and pass it in.

	* e-tree-model.c: Removed an unused variable.
