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

the ISO 639 codes associated with that language name.

This function adds language name (as index) and its code (as a table element) tousing thean appropriate placeindex in the temp tablenumber.

<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, ...2B, 3 ..., 5 ... Note<part> thatfor partthe 5override codesdata gois inprefixed indexwith [4]'O'

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).
