/**
 * This is to demonstrate cloning.
 * ToClone has one int field called "field" which showField() prints.
 * SimpleCloneMe() uses the default via super.clone()
 * and fancyCloneMe() uses a custom clone() method.
 * To understand this test you'll also have to study the actual
 * cloning source in ToClone.java.
