 * <p>Works with {@link ToStringBuilder} to create a "deep" <code>toString</code>.</p>
 *
 * <p>To use this class write code as follows:</p>
 *
 * <pre>
 * public class Job {
 *   String title;
 *   ...
 * }
 *
 * public class Person {
 *   String name;
 *   int age;

 *
 *   public String toString() {
 *     return new ReflectionToStringBuilder(this, new RecursiveToStringStyle()).toString();
 *   }
 * }
 * </pre>
 *
 * <p>This will produce a toString of the format:
 * <code>Person@7f54[name=Stephen,age=29,smoker=false,job=Job@43cd2[title=Manager]]</code></p>
 *
 * @since 3.2
