V7 - 1. fixed the file XXX_case2b_CLmax_WT_cpcf.dat, which had several problems:
        (N should be provided in DATASETAUXDATA lines near the top, and not in the main part of the data files)
        (The zone titles incorrectly said case2a)
     2. fixed ZONE title info in XXX_case2b_CLmax_WT_unsteadypressures.dat (case2a -> case2b)
     3. fixed ZONE title info in XXX_case2b_CLmax_WT_velocity.dat (case2a -> case2b)
