49 * This class is a concept container and holds a map of concepts. The {@link PfConceptContainer} class implements the
50 * helper methods of the {@link PfConceptGetter} interface to allow {@link PfConceptContainer} instances to be retrieved
51 * by calling methods directly on this class without referencing the contained map.

54 * Each concept entry is checked to ensure that its key and value are not null and that the key matches the key in the
55 * map value. Each concept entry is then validated individually.
