--    This module allows templates to use translations from the shared Datasets on Commons
--
--
--    For example, this will use dataset https://commons.wikimedia.org/wiki/Data:Original/Template:Graphs.tab
--    The "msg" function uses a Commons dataset to translate a message
--    to translate message with ID "source-table" with an argument $1 = "tablename" to a wikitext
--    with a given key (e.g. source-table), plus optional arguments
--    to the wiki markup in the current content language.
--
--
--      {{#invoke:TNT | msg | Original/Template:Graphs.tab | source-table | tablename}}
--      {{#invoke:TNT | msg | Original/Template:Graphs.tab | source-table | param1 }}
--            uses https://commons.wikimedia.org/wiki/Data:Original/Template:Graphs.tab
--   
--   
--    The "doc" function will generate the <templatedata> parameter documentation for templates.
--    This way all template parameters can be stored and localized in a single Commons dataset.
--    NOTE: "doc" assumes that all documentation is located in Data:Templatedata/* on Commons.
--
--      {{#invoke:TNT | doc | {{BASEPAGENAME}} }}
--            uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab
--            if the current page is Template:Graph:Lines/doc
