26   * Base abstraction for any Design Pattern type whose structure is based on 
27   * surrogation or wrapping. Surrogate Design Patterns are those that for some 
28   * purpose wrap and provide to clients the same interface view of the actual 
29   * wrapped <code>Component</code> interface. <br/><br/>
30   * 
31   * Structural surrogate Patterns are:
32   * 
33   * <ul>
34   * <li>Adapter Pattern</li>
35   * <li>Composite Pattern</li>
36   * <li>Decorator Pattern</li>
37   * <li>Proxy Pattern</li>
