Exercise 7.8 (P191)

Many GUIs provide a table widget with a stateful multi-tier sort: the primary sort key is the most recently clicked column head, the secondary sort key is the second-most recently clicked column head, and so on. Define an implementation of sort.Interface for use by such a table. Compare that approach with repeated sorting using sort.Stable.
