19   * An object which can be combined with other similar objects to form a
20   * composite object.  Usually, the components implement a shared interface that
21   * is also implemented by the Composite.  See "Design Patterns" by Erich Gamma,
22   * Richard Helm, Ralph Johnson and John Vlissides for more information.
23   * 
24   * <p>This interface is an optional marker interface which you may use to
25   * specify that an object is a component of a larger composite.  It is not
26   * required that you use or reference this interface to utilize the Composite
27   * package.
