Deleted file repeated information in participant_data_140117.csv, from what I could judge, so there's no use in having it there
renames taking away date of creation from file name. that's an information that is there for free using CVS
The only true changes to the participant_data file is the addition of certain values in the exclude variable, based on my comments about how participants carried out the nonlinguistic task. other changes are just about unintended reordering of rows.
