23   * A plugin Strategy pattern which will detect the plural property which
24   * maps to a singular property name.
25   * This Strategy is used when composite properties (such as properties
26   * of type Collection, List, Iterator, Enumeration) are used as we need to
27   * match the adder-method, which typically uses a singular name.
28   * This interface allows a variety of different implementations to be used.
