 *  &#064;JsonView(BasicView.class)
 *</pre>
 * which would specify that property annotated would be included
 * when processing (serializing, deserializing) View identified
 * by <code>BasicView.class</code> (or its sub-class).
 * If multiple View class identifiers are included, property will
 * be part of all of them.
 *<p>
 * Starting with 2.9, it is also possible to use this annotation on
 * POJO classes to indicate the default view(s) for properties of the
 * type, unless overridden by per-property annotation.
