trialfun modified to correct for subjects whom have 2 trigger 15's within one trial
trigger 15 = end of audiofile
This does not fix the other problems where most triggers are wrong. For that we use trialfun_auditory_audio_onoff. However, this latter function will not mark lthe locations of 1st word and target word onsets.
