[Eeglablist] Understanding topoplot

Hi Joaquin,

topoplot() is plotting the activity at a certain time (or an average over a
certain time window) at all channels, and interpolated between channels.
I've never used it to plot activity restricted to a certain frequency,
although in principle I guess that is possible; I've only used it to plot
the raw ERP amplitudes, though.
