/**
 * Extensions can be used to share common setup and tear down behavior across different specifications.
 * For example, given a normal java class with some JUnit setup and tear down methods:
 * 
 * <pre class="prettify">
 * public class ExtensionExample {
 *   @BeforeClass
 *   public static void beforeClass(){
 *     System.out.println("before Class");
 *   }
 * 
 *   @Before
 *   public void before(){
 *     System.out.println("before");
 *   }
 * 
 *   @AfterClass
 *   public static void afterClass(){
 *     System.out.println("after Class");
 *   }
 * 
 *   @After
 *   public void after(){
 *     System.out.println("after");
 *   }
 * }
 * </pre>
 * 
 * When you declare an instance of this class
 * as an extension field in your spec, all the setup
 * and tear down methods will be executed before/after
 * each fact/spec, respectively:
