/** This program will practice with an interface.  We have 4 arrays that

 *  arrays:  find their maximum and average.
 *  We have a separate calculator class that knows how to find the maximum
 *  or average of any array, so we call the calculator's getMaximum()
 *  and getAverage() on each array.
