This class enables one to store an entry in the defaults table that's constructed each time it's looked up with one of the `getXXX(key)` methods. Here's an example of an `ActiveValue` that constructs a `DefaultListCellRenderer`:

      Object cellRendererActiveValue = new UIDefaults.ActiveValue() {
          public Object createValue(UIDefaults table) {
              return new DefaultListCellRenderer();
          }
      };

      uiDefaultsTable.put("MyRenderer", cellRendererActiveValue);
