+    The default implementations of this method is an <a

+    relation</a>:
+      <ul>
+      <li>It is reflexive: for any instance <code>x</code> of type <code>Any</code>,

+      <li>It is symmetric: for any instances <code>x</code> and <code>y</code> of type 
+      <code>Any</code>, <code>x.equals(y)</code> should return <code>true</code> if and only 
+      if <code>y.equals(x)</code> returns <code>true</code>.</li>

+    If you override this method, you should verify that

+    "equal" (<code>o1.equals(o2)</code> returns <code>true</code>)
