55 * This class is a concept container and holds a map of concepts. The {@link PfConceptContainer} class implements the
56 * helper methods of the {@link PfConceptGetter} interface to allow {@link PfConceptContainer} instances to be retrieved
57 * by calling methods directly on this class without referencing the contained map.
59 * <p>Validation checks that a container key is not null. An error is issued if no concepts are defined in a container.
60 * Each concept entry is checked to ensure that its key and value are not null and that the key matches the key in the
61 * map value. Each concept entry is then validated individually.
63 * @param C the concept being contained
