--[=[-------------------------< _ N A T I V E _ N A M E >------------------------------------------------------ implements {{native name}}; entry point from a module <args_t> is a table of parameter name/value pairs. Parameters that are supported are: args_t[1] - IETF language tag (required) args_t[2] - the native name (required) args_t.italic - accepts string values 'no' or 'off'; expects 'no' so 'off' must be translated args_t.italics - alias of |italic= args_t.paren - accepts 'omit', 'off', or 'no' args_t.icon - alias of paren args_t.parensize - args_t.fontsize - deprecated alias of |parensize= args_t.nolink - any value inhibits wikilinking of language name args_t.suppress_empty_list_error - when set to 'yes', suppresses an 'empty' error message; mostly for use within another template

this function calls these functions in Module:lang: _is_ietf_tag _lang _name_from_tag

TODO: add support for romanization and transliteration? add support for postfix so that 'mis' can render something like this: Chotilapacquen (Coahuiltecan)
