MultidimensionalCounter.getCounts(int) returns wrong array of indices
---------------------------------------------------------------------

                 Key: MATH-552
                 URL: https://issues.apache.org/jira/browse/MATH-552
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 2.2
         Environment: Java 1.6
            Reporter: James Bence
            Priority: Minor


MultidimensionalCounter counter = new MultidimensionalCounter(2, 4);
for (Integer i : counter) {
    int[] x = counter.getCounts(i);
    System.out.println(i + " " + Arrays.toString(x));
}

Output is:
0 [0, 0]
1 [0, 1]
2 [0, 2]
3 [0, 2]   <=== should be [0, 3]
4 [1, 0]
5 [1, 1]
6 [1, 2]
7 [1, 2]   <=== should be [1, 3]
