[Eeglablist] Pre and post stimuli compariso

[Stephen Politzer-Ahles]

In EEGLAB you could just use pop_selectevent to separate these into two
conditions--use the same trigger event for each one, but for the first use
the latencies [-1 0] and for the second use the latencies [0 2.3]; then you
could compare the two conditions in whatever way you had planned.

Best,
Steve
