Added e-selection-model-array.lo.

2001-03-25  Christopher James Lahey  <clahey@ximian.com>

	* gal/Makefile.am (libgal_la_LIBADD): Added
	e-selection-model-array.lo.

	* gal/widgets/Makefile.am: Added e-selection-model-array.c and
	e-selection-model-array.h.

	* gal/widgets/e-selection-model-array.c,
	gal/widgets/e-selection-model-array.h: New class that implements
	the details of ESelectionModel.  ESelectionModel has been
	refactored to just be a this virtual class.  ESelectionModelArray
	is the original implementation of ESelectionModel.  This is what
	most people will want to use or derive from.

	* gal/widgets/e-selection-model-simple.c,
	gal/widgets/e-selection-model-simple.h: Made the parent class of
	this be ESelectionModelArray instead of ESelectionModel.  Changed
	some function names to match this change.

	* gal/widgets/e-selection-model.c,
	gal/widgets/e-selection-model.h: Refactored most of the
	implementation of this class into ESelectionModelArray.  Now just
	a thin virtual class.

From gal/e-table/ChangeLog:

2001-03-25  Christopher James Lahey  <clahey@ximian.com>

	* e-table-selection-model.c, e-table-selection-model.h: Made the
	parent object of this be ESelectionModelArray instead of
	ESelectionModel due to their refactoring.  Changed the commented
	out code for saving the selection a bit.
