/**
 * Defines a functor interface implemented by classes that create objects.
 * <p/>
 * A <code>Factory</code> creates an object without using an input parameter.
 * If an input parameter is required, then {@link Transformer} is more appropriate.
 * <p/>
 * Standard implementations of common factories are provided by
 * {@link FactoryUtils}. These include factories that return a constant,
 * a copy of a prototype or a new instance.
