-Arranges widgets in a grid.
-
-This layout class places widgets in a grid, lining up their edges in rows and
-columns.  Widgets are placed on rows left-to-right and rows are placed top-to-
-bottom.
-
-The start of each row must be indicated manually.  Individual cells can be
-skipped to leave them empty.
