primary table of tables that decode:
	lang -> language tags and names
	script -> ISO 15924 script tags
	region -> ISO 3166 region tags
	variant -> iana registered variant tags
	suppressed -> map of scripts tags and their associated language tags
	
all of these data come from separate modules that are derived from the IANA language-subtag-registry file

key_to_lower() avoids the metatable trap and sets all keys in the subtables to lowercase. Many language codes
have multiple associated names; Module:lang is only concerned with the first name so key_to_lower() only fetches
the first name.

For internationalization; not used at en.wiki

The language names taken from the IANA language-subtag-registry file are given in English. That may not be ideal.
Translating ~8,000 language names is also not ideal.  MediaWiki maintains (much) shorter lists of language names
in most languages for which there is a Wikipedia edition.  When desired, Module:Lang can use the MediaWiki 
language list for the local language.

Caveat lector: the list of MediaWiki language names for your language may not be complete or may not exist at all.
When incomplete, MediaWiki's list will 'fall back' to another language (typically English).  When that happens
add an appropriate entry to the override table below.

Caveat lector: the list of MediaWiki language names for your language may not be correct.  At en.wiki, the
MediaWiki language names do not agree with the IANA language names for these ISO 639-1 tags.  Often it is simply
spelling differences:
	bh: IANA: Bihari languages MW: Bhojpuri – the ISO 639-3 tag for Bhojpuri is bho
	bn: IANA: Bengali MW: Bangla – Bengali is the exonym, Bangla is the endonym
	dv: IANA: Dhivehi MW: Divehi
	el: IANA: Modern Greek MW: Greek
	ht: IANA: Haitian MW: Haitian Creole
	ky: IANA: Kirghiz MW: Kyrgyz
	li: IANA: Limburgan MW: Limburgish
	or: IANA: Oriya MW: Odia
	os: IANA: Ossetian MW: Ossetic
	"pa: IANA: Panjabi MW: Punjabi
	"ps: IANA: Pushto MW: Pashto
	"to: IANA: Tonga MW: Tongan
	"ug: IANA: Uighur MW: Uyghur
use the override table to override language names that are incorrect for your project

To see the list of names that MediaWiki has for your language, enter this in the Debug colsole:
	=mw.dumpObject (mw.language.fetchLanguageNames ('<tag>', 'all'))
(replacing <tag> with the language tag for your language)

Use of the MediaWiki language names lists is enabled when media_wiki_override_enable is set to boolean true.

local media_wiki_override_enable = false;										-- set to true to override IANA names with MediaWiki names; always false at en.wiki
