temp table is a table of tables where the key is the language name and the value is a 3-element table listing

the ISO 639 codes associated with that language name.

This function adds language name (as index) and its code (as a table element) to the appropriate place in the temp table.

lang is the language name from the source data

code is the associated ISO 639 code from the source data

part is 1 for ISO 639-1 language names and codes, 2 ..., 3 ..., 5 ... Note that part 5 codes go in index [4]

This function does not create alias entries in temp table for those language names that use characters with diacritics.

To do so risks conflict between names that do not use diacritics (Bari, code bfa) and names that do (Barí, code mot).

if not temp[lang] then -- when no entry for this language

temp[lang] = {'""', '""', '""', '""'}; -- make a blank entry

end

temp[lang][part] = table.concat ({'"', code, '"'}); -- add the code
