function tilefigs(figs)
%TILEFIGS Tile all open figure windows around on the screen.
%
%   TILEFIGS places all open figure windows around on the screen with no
%   overlap.
%
%   TILEFIGS(FIGS) can be used to specify which figures that should be
%   tiled. Figures are not sorted when specified.
%
%   See also SORTFIGS, CYCLEFIGS.
