  /**
   * Object Reflector API.
   *
   * <p>
   * The job of the reflector is to create the meta-model, typically using annotations and
   * other conventions in its own applib.
   *
   * <p>
   * Concrete implementations are in the <tt>programmingmodel-xxx-impl</tt> modules.  These
   * are expected to be based heavily on <tt>ObjectReflectorAbstract</tt>, defined in
   * <tt>nof-core</tt>.  This implementation defines two further sub-APIs which are based on
   * the {@link org.apache.causeway.core.metamodel.facetapi.Facet}s and {@link org.apache.causeway.core.metamodel.facetdecorator.FacetDecorator}s:
   * <ul>
   * <li> the {@link ProgrammingModelInstaller} is used to specify the collection of {@link org.apache.causeway.core.metamodel.facets.FacetFactory}s
   *      that will be used to actually process and build up the metamodel.
   * <li> the {@link FacetDecoratorInstaller} API specifies how {@link org.apache.causeway.core.metamodel.facetapi.Facet}, once created,
   *      can be additionally decorated to modify their behaviour.  A number of other components are implemented as
   *      {@link org.apache.causeway.core.metamodel.facetdecorator.FacetDecorator}s, such as {@link org.apache.causeway.authorization.AuthorisationFacetDecorator authorisation},
   *      {@link org.apache.causeway.help.HelpFacetDecorator help}, and {@link org.apache.causeway.transaction.facetdecorator.TransactionFacetDecorator transactions}.  However
   *      it is possible for other {@link org.apache.causeway.core.metamodel.facetdecorator.FacetDecorator}s to be defined and installed also (such as <tt>i18n</tt>).
   * </ul>
