update libsvm train and test function to properly work in multiclass classifications #28

In multiclass problems, train_libsvm transform labels to 0, 1 and mistakenly change it to two-class classifications. Also, test_libsvm considers predicted labels as 0 and 1, which is incorrect in a multiclass classification problem.
