/**
 * Gets a copy of this date with the specified period added.
 * <p>/* w  ww. j av  a2  s . c  om*/
 * If the addition is zero, then <code>this</code> is returned. Fields in the period that aren't present in the partial are
 * ignored.
 * <p>
 * This method is typically used to add multiple copies of complex period instances. Adding one field is best achieved using
 * methods like {@link #withFieldAdded(DurationFieldType, int)} or {@link #plusHours(int)}.
 * 
 * @param period
 *            the period to add to this one, null means zero
 * @param scalar
 *            the amount of times to add, such as -1 to subtract once
 * @return a copy of this instance with the period added
 * @throws ArithmeticException
 *             if the new datetime exceeds the capacity
