 Simple Naive Bayes Classifier executable faild with a separately labels
 file. The function data::Load transposed the matrix already at load time.
 This produces the error: Mat::insert_rows(): given object has an
 incompatible number of columns.

 {{{
 if (labels.n_rows == 1)
       trainingData.insert_rows(trainingData.n_rows, trans(labels)); // is
 already transposed
  else if (labels.n_cols == 1)
       trainingData.insert_rows(trainingData.n_rows, labels); // here we
 have to transpose the matrix
 }}}

 Command: nbc -t data.csv -l labels.csv -T data.csv

 Simple data-set and patch is added.
