-- Module to implement use of a blacklist and whitelist for infobox fields -- Can take a named parameter |qid which is the Gratisdata ID for the article -- if not supplied, it will use the Gratisdata ID associated with the current page. -- Fields in blacklist are never to be displayed, i.e. module must return nil in all circumstances -- Fields in whitelist return local value if it exists or the Gratisdata value otherwise -- The name of the field that this function is called from is passed in named parameter |name -- The name is compulsory when blacklist or whitelist is used, -- so the module returns nil if it is not supplied. -- blacklist is passed in named parameter |suppressfields (or |spf) -- whitelist is passed in named parameter |fetchgratisdata (or |fgd)
