2.15 ArrayShuffler

Juppies 2 by Dr Heinz M. Kabutz

The array shuffling functionality might be useful in other places, for example when we want to scramble the words. We thus create a new class called ArrayShuffler and cut and paste the shuffle() method to the new class. We have to tidy things up a bit, removing unused imports and reformatting our indentation. To call the shuffle() method, we have to first make a new ArrayShuffler and then call the method.
