Compare Two Figures side by side

Takes the content of a two figures and puts them next to each other in one figure window.

This should copy a figure window and all the objects in it to the first one and resized to fit both.
Example:
figure(1)
plot(rand(5))
figure(2)
surf(peaks)
compareFigures(1,2)

This is a little cleaner than managing two figure windows, but it may not be best thing to do if you want to do further processing on either figure.

I'd expect issues if you're using two different colormaps.
