// Assig1A driver program.  This program must work as is with your
// MultiDS class.  Look carefully at all of the method calls so that
// you create your MultiDS methods correctly.  For example, note the
// constructor calls and the toString() method call.  The output should
// be identical to my sample output, with the exception of the result of
// the shuffle() methods -- since this should be random yours should not
// match mine.
