Detailed Description

User interface class.

This is the beginnings of a class to handle user interface things.

Eg under a GUI, you may want to show an hourglass when doing a lot of database activity. DbQuery knows about DbUserInterface and calls SetWait() and ClearWait(), so if you register some functions that create and destroy an hourglass you will get them at sensible times.
