class SmartRestrictedMemberReader extends RestrictedMemberReader
SmartRestrictedMemberReader is a subclass of
RestrictedMemberReader which caches the access rights
per children's list. We place them in this throw-away object
to speed up partial rollup calculations.
The speed improvement is noticeable when dealing with very big dimensions with a lot of branches (like a parent-child hierarchy) because the 'partial' rollup policy forces us to navigate the tree and find the lowest level to rollup to and then figure out all of the children on which to constraint the SQL query.
