--Determine the required CSS class to display coordinates

Usually geo-nondefault is hidden by CSS, unless a user has overridden this for himselfdefault is the mode as specificied by the user when calling the templatemode is the display mode (dec or dms) that we will need to determine the css class for

local function displayDefault(default, mode) if default

"" then default = "dec" end

if default

mode then return "geo-default" else return "geo-nondefault" endend

--specPrinter

Output formatter. Takes the structure generated by either parseDecor parseDMS and formats it for inclusion on Wikipedia.
