/**
 * <p>
 * Checks that an overriding {@code clone()} method invokes {@code super.clone()}.
 * Does not check native methods, as they have no possible java defined implementation.
 * </p>
 * <p>
 * Reference:
 * <a href="https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/Object.html#clone%28%29">
 * Object.clone()</a>.
 * </p>
 * <p>
 * To configure the check:
 * </p>
 * <pre>
 * &lt;module name=&quot;SuperClone&quot;/&gt;
 * </pre>
 * <p>Example:</p>
 * <pre>
 * class A {
 *
 *  public Object clone() { // OK
 *   return super.clone();
 *  }
 * }
 *
 * class B {
 * private int b;
 *
 *  public B clone() { // violation, does not call super.clone()
 *   B other = new B();
 *   other.b = this.b;
 *   return other;
 *  }
 * }
 *
 * class C {
 *
 *  public C clone() { // OK
 *   return (C) super.clone();
 *  }
 * }
 * </pre>
 * <p>
 * Parent is {@code com.puppycrawl.tools.checkstyle.TreeWalker}
 * </p>
 * <p>
 * Violation Message Keys:
 * </p>
 * <ul>
 * <li>
 * {@code missing.super.call}
 * </li>
 * </ul>
