[Eeglablist] CSD maps.

[Christopher Summerfield]

hi Arno,

looking at the code for topoplot() and headplot() it seems that there's no
option to plot a CSD (current source density) map.  I guess that what's
involved is taking the 2nd
derivative across the interpolated scalp data...in 2 dimensions?  do you
have code to do this, or can you suggest how I might do it?
thanks
chris
