%%    USER COMMANDS
%%    \usepackage{figsize}
%%        If option distort is present then the included images will
%%        be allowed to have different x & y scaling.  Otherwise
%%        the aspect ratio will be kept.
%%
%%    \SetFigLayout[extra lines of space to add]{rows}{cols}
%%    To set the sizes of graphics relative to the page size in a
%%    cell of a matrix with rows and cols specified.  Optional
%%    integers can be specified to increase the space allowed for
%%    captions.  If a value of 8 is placed, then 8 extra lines of
%%    caption text will be allowed for.
%%
%%    \includegraphics{file}
%%    To include the graphics with the current most size settings.
