Revision 34

	* Thuban/UI/tableview.py: Add some doc-strings
	(TableGrid):
	(TableGrid.OnRangeSelect):
	(TableGrid.OnSelectCell):
	(TableFrame.__init__):
	(TableFrame.row_selected):
	Selecting rows in the grid view now updates the selected shapes
	through the TableFrame. To achieve this we derive TableGrid from
	Publisher and introduce the message type ROW_SELECTED which the
	TableFrame subscribes to and which is issued by OnRangeSelect and
	OnSelectCell

	(DataTable.SelectRow): Removed because it's no longer needed in
	the row/shape selection scheme
