Changes in VALD3 configuration file.

The VALD configuration file describes the data files. One line corresponds to a single data file. The first line contains wavelength window and the reference wavelength for line identification, maximum ionization stage and the maximum excitation potential for the lower level in eV. Wavelength window scales with the wavelength but not more then by a factor of 100: dwl = min(max(dwl*wl/wl_ref, dwl_ref*0.01), dwl_ref*100).

Any consecutive line starting with semicolon are interpreted as comments. Each line starts with filename complete with a path relative to VALD home directory. Next parameter is a unique number of the line list in the configuration file. This number is only used for association of the list name and extracted data field and thus does not have to be consistent between different configuration files. The two next entries are give range of species included in the file using the VALD unique species number. This is the reason why species number in the VALD species list must be monotonous!

The next entry is new: it is a flag that indicates that the list can be merged (0) or is exempt from any merger (1).

The rest of the line is as before: 9 weights starting from the wavelength and the short name of the line list.
