    This function prints pressure level based output to appropriate files.  It writes 
    interpolated values for a user defined pressure level structure. The data lines in 
    the output file have pressure as the first variable.  Input data are taken from the 
    University of Wyoming web site, the NOAA archive, or other source of upper air files.
    If input data are in m/s "uncomment" the appropriate lines near the end.
