A named KnowledgeWorks CLOS class is defined by the macro def-named-kb-class which is syntactically identical to the Common Lisp
macro, and semantically identical with the exception that it adds a KnowledgeWorks mixin class named-kb-object if none of the superclasses already contains
it, and makes the default name for the objects be a symbol generated from the class name. Classes defined by def-named-kb-classcontain a
slot which those defined by def-kb-class do not.
