final object OverridingPairs

A module that can produce a kind of iterator (Cursor), which yields all pairs of overriding/overridden symbols that are visible in some baseclass, unless there's a parent class that already contains the same pairs.

Adapted from the 2.9 version of OverridingPairs. The 2.10 version is IMO way too unwieldy to be maintained.
