The implementation assumes classes are 0-indexed, not 1-indexed. You
should set numClasses = 3 and change your labels to 0, 1, 2.

I am testing decision tree using iris.scale data set
(http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/multiclass.html#iris)
In the data set there are three class labels 1, 2, and 3. However in the
following code, I have to make numClasses = 4. I will get an
ArrayIndexOutOfBound Exception
