Module entry point

Crude documentation tool that returns one of several lists of language codes and names.

--[[--< A L I A S _ N A M E S _ G E T >

returns list of aliases for metaparameter returns empty string when there are no aliases returns empty string when name not found in alias_src{} or id_src{}; access icon parameters have no aliases so ignored

metaparameter is the key in Module:Citation/CS1 aliases{} table or id_handlers{} table.

Some lists of aliases might be better served when a particular alias is identified as the canonical alias for a particular use case. If, for example, Perodical lists: 'journal', 'magazine', 'newspaper', 'periodical', 'website', 'work' that order works fine for {{cite journal}} documentation but doesn't work so well for {{cite magazine}}, {{cite news}}, or {{cite web}}. So, for using this function to document {{cite magazine}} the returned value should be the aliases that are not best suited for that template so we can specify magazine in the override (frame.args[2]) to be the canonical parameter so it won't be listed with the rest of the aliases (normal canonical journal will be)

must exist in the alias list except: when value is 'all', returns the canonical parameter plus all of the aliases

output format is controlled by |format= plain - renders in plain text in a tag; may have id attribute para - renders as it would in {{para| }} when not specified, refurns the default bold format used for {{csdoc}}
