function mmpage(arg)
%MMPAGE GUI to Set Figure Paper Position.
% MMPAGE allows the user to set the current figure
% position on the printed page using a gui.
% MMPAGE(Hf) places the figure having handle Hf.
%
% Editable text boxes: Left Bottom Width Height
% sets the respective figure position on the page.
% Pushbuttons:
%  Set Default makes the current position default for future figures.
%  Get Factory changes the figure position to factory values.
%  L/R Center centers the figure Left to Right.
%  U/D Center centers the figure Up to Down.
%  WYSIWYG makes the Width and Height identical to the Figure Window.
%  Get Default sets the figure position to the Default values.
%  Revert restores the figure position to that when MMPAGE was called.
%  Done closes the MMPAGE GUI.
%
% Usage: create figure, call MMPAGE, then print.
