-- the following code extracts the result from either:
-- (a) a LuaVariables result stored earlier on the page; or
-- (b) a LuaCache object of the lowercase name; or finally
-- (c) an actual Cargo query to retrieve the information from the page
-- we avoid doing a Cargo query at all costs because Cargo queries are extremely expensive
-- this was not premature optimization; the wiki was actually experiencing errors
-- prior to this optimization being added
-- this code was adapted from Module:Team on Leaguepedia
-- contact River for questions
