[FieldTrip] Automatic artifact detection (no rejection)

[Robin Kramer]

Hi Steve and Phil,

Thank you, that is exactly what I was looking for. However, it seems as if
it not yet implemented in ft_artifact_threshold(). I see no difference
between the amount of rejected trials. Moreover, the option is not
specified on the reference page, though it is on ft_artifact_eog for
instance. Is that correct?

Best,
Robin
