--    Development Tactic on 20180905
--    A central module could need a translation service and a versioning service to enhance its functions or its stability without disturbing the preview normal use.
--    A main module can define its sought sub-modules versions names and its known sub-modules versions names.
--    The Library:versions installs other libraries, supports versions, binds modules, libraries and i18n translations.
--    A central module and its translations can inpedendently change. Its p.version{} identifications change also.
--    For this goal a module contains at least one i18n tranlations table. Its /I18N sub-modules contains translations in several languages.
--    Central Libraries, like modules, contain their own p.version{} identifications and i18n translations in Module:Library/library_name/I18N.
--    The adaptation to any number of languages is automatic.
--    The highest level is the main module. The lowest level is the libraries level.
--
--    Any module or library can contain i18n tables.
--    i18n tables are mixed from the lowest to the highest level, to permit at upper module to adapt the meaning of string to a new use.
--    Each library is independent of other ones and they can be mixed in any order.
--    To avoid conflict of translations keys between libraries, all translations keys names start with the library name.
--
--    Tactic for modules, arguments, options and default values 20180908.
--    In all cases the main module protects all original tables, including for itself.
--    Permit modules without versions for many existing modules. Modules are also simply tables for data-modules or PageData in Json.
--    3 central functions bind sub-modules, translations and arguments in 3 new tables.
--    All arguments can have default values, like "prop_default" for "prop" to use it in case of tests or missing value.
--    Do not disturb actual modules, libraries, translations ; only add new structures and most explicit tables of args, i18n, modules, libraries...
--
-- - - - ------------------ - - - - ------------------ - - - - -----------------------------

--    The central system permits to convert any module as central.
--    The Lua part of the central modules support contains some libraries used by central modules.
--    The Module:Centralizer installs central libraries (waiting stable Scribunto central repository).
--    An object has a function object.new() to form several objects
--    A library is unic and come from Scribunto.

--    This library supports modules to: function versions.
--    * Collect and bind modules and sub-modules depending from their p.version{}
--    * Collect and bind translations from modules or libraries itself, and their /I18N sub-modules
--    * Formats parametrable strings_c
--    * Add a language needs only to add its own i18n subtable, like i18n.en = {}
--    * Manage alternate versions of sub-modules sought in main, like Module:Sub, Module:Sub.2.1, Module:SubPlus.
--    A central module and its translations can inpedendently change. Its p.version{} identifications change also.
--    For this goal a module contains at least one i18n tranlations table. Its /I18N sub-modules contains translations in several languages.
--    Central Libraries, like modules, contain their own p.version{} identifications and i18n translations in Module:Library/library_name/I18N.
