[Eeglablist] plotting topographies for an average time window and for the difference between conditions

[David Groppe]

Hi Seba,
   James's script should do the trick, but if you still want to use
the Mass Univariate Toolbox, let me know what problems you've been
having with adding bin information and I will try to help you out.
        cheers,
           -David
