Programming concept: BaseInteractor, VerboseInteractor
Classes that help to gather sucesses and failures.
An object of one of these, or a local flavour for the BaseInteractor, is meant
to connect programs to the internal processing of a KIP Document.
Please see the inline documentation of BaseInteractor for details.  General
topics of concern are:
- Passphrase collection
 - Key tab filename configuration
 - Reports on signature creation, validation
 - Reports on trusted content
 - Reports on muddled content creation and and making Mud readable
 
The VerboseInteractor is just one that mindlessly blurts out all that it gets.
