Detailed Description

Helper base class: object descriptions for error messages and such.

Classes derived from namedclass have a class name (such as "transaction"), an optional object name (such as "delete-old-logs"), and a description generated from the two names (such as "transaction delete-old-logs").

The class name is dynamic here, in order to support inheritance hierarchies where the exact class name may not be known statically.

In inheritance hierarchies, make namedclass a virtual base class so that each class in the hierarchy can specify its own class name in its constructors.
