 Often in mlpack's supervised learning methods, the type
 `arma::Col<size_t>` is used to hold labels.  However, data is column-
 major, which means each dimension is a row.  Therefore, it makes sense
 that labels should also be a row, and the type `arma::Row<size_t>` should
 be used instead.

 The reason that `arma::Col<size_t>` was originally used was convenience.
