Title: Audit observer

This branch implements an auditing system which lets you find out which values were read, what potential values were available from all of the levels and which value was chosen.

This task is tricker than expected in order to support nested values.

This branch changes the `EventHandler` interface, but results in far simpler implementation for the command line output.
