-- getIntersectCat takes most of the usual parameters.
-- The usual whitelisting, blacklisting, onlysourced, etc. are implemented
-- It takes two properties, |prop1 and |prop2 (e.g. occupation and country of citizenship)
-- Each property's value is a wiki-base entity
-- For each value of the first parameter (ranks implemented) it fetches the value's main category
-- and then each value of the second parameter (possibly substituting a simpler description)
-- then it returns all of the categories representing the intersection of those properties,
-- (e.g. Category:Actors from Canada). A joining term may be supplied (e.g. |join=from).
-- The item's P734 (family name) is the sort key, or no sort key if there is no family name.
-- The sort key may be overridden by the parameter |sortkey (alias |sk).
