 * Usage example:

 *
 * <pre>
 * import static org.codelibs.core.lang.ClassIterator.*;
 *
 * Class&lt;?&gt; someClass = ...;
 * for (Class&lt;?&gt; clazz : iterable(someClass)) {
 *     ...
 * }
 * </pre>

 * By default, the {@link Object} class is also included in the iteration. If you do not want to include {@link Object},
