7 * This method is like `_.clone` except that it accepts `customizer` which
8 * is invoked to produce the cloned value. If `customizer` returns `undefined`,
9 * cloning is handled by the method instead. The `customizer` is invoked with
10 * up to four arguments; (value [, index|key, object, stack]).
