[Eeglablist] Event out of data boundary

[Michelle Lee]

Hello Makoto, I managed to run through the pipeline without having one of
my events be 'out of boundary' after epoching. I'm not entirely sure why,
but the reason it was doing this was because in my bin descriptor file, I
had the format like this:
.{119;129}.{1}
when it should have been like this:
.{119;129}{1}

The latter means to accept these events (corresponding to these codes) only
if followed by a 1 (correct answer). I'm not too sure what the first format
is telling eeglab to do, but I suspect that was the reason why one of my
events was being removed.
