Remove default scaling of the system. The scaling doens't seem to help actual solutions. One example that fails in the flexural code. With large timesteps the solutions seems to blow up. One particular example is profilePresentation on the tdb_presentation_figures branch with k = 0.0005

% setFontSize(fig, pts)
% Sets all fontsizes within a figure to size pts
% The default value for pts is 16.
function setFontSize(fig, pts)
    default_arg('pts', 16);
    set(findall(fig,'-property','FontSize'),'FontSize',pts);
end
