 * Mock class for NAN HAL. Provides access to HAL API and to callbacks. To
 * extend:
 * <ul>
 * <li>HAL API: create a {@code public void} method which takes any fixed
 * arguments (e.g. a {@code short transactionId} and a second argument to
 * provide the rest of the argument as a JSON string: {@code String jsonArgs}.
 * <li>Callbacks from HAL: create a {@code public static native} function which
 * is used to trigger the callback from the test harness. The arguments are
 * similar to the HAL API arguments.
