db.pl -- kLog database interface

This module provides access to the extensional database. Currently it just consults a Prolog database ensuring that facts are loaded into the db namespace.

Syntactical conventions
The extensional declarations should use the special predicate interpretation/2 whose first argument is an identifier for the interpration (any Prolog term) and whose second argument is a fact.
