-- Module:PageViews (preprocess variant)
-- Live page view count via Extension:HitCounters' {{NUMBEROFVIEWS:Title}}.
-- Usage:
--   {{#invoke:PageViews|get}}                         -- current page, localized
--   {{#invoke:PageViews|get|page=Main Page}}          -- specific page, localized
--   {{#invoke:PageViews|get|page=Main Page|plain=yes}}-- just the number
--   {{#invoke:PageViews|get|page=Foo|fallback=0}}     -- fallback if unavailable
