[Eeglablist] Peak picking

I've written (somewhat clumsily) such a tool that lets you rbbox() an area
of a plot - I use it on butterfly plots - and then calculates min, max &
(max - min) for each data series in the rbbox area. It then stamps out
either an unsorted or sorted (by peak height) list of data series names
in a separate GUI window, with the min, max, etc. stats of each. The whole
thing runs as the WindowButtonDownFcn of the butterfly plot figure window.

Right now I'm less than three months (!!) from finishing up my masters
thesis, so I don't really have time to turn it into a plugin. I'll have a
go after December 31st, though, if anyone would like such a beast.

Call it my penance for getting all the lovely ICA functionality of EEGLAB,
for all these months... :>
