adding ldeo_magic test
in the midst of making IODP_csv.  added parse_args so I can have extra arguments in the ex_out class.  it means that they have to be "none" not NONE, because of the way I'm doing it, but I don't think that will get in the way any. longest message ever
finished IODP_csv test, starting PMD_magic test
