+Future events (i.e. "current" status) should take place in the current or
+following year. E.g. We should have events in January next year appear when it
+is December of the current year.
+
+This code creates 2-3 lists: One of current years and a list of current events
+for each year (namespaced with "future" to prevent collisions). Later we loop
+through these lists to generate our event info.
