Let's implement DataFrame sorting:

<V extends Comparable<? super V>> DataFrame sort(DataRowToValueMapper<V> m)

DataFrame sortByColumn(String column, boolean ascending)
DataFrame sortByColumn(int column, boolean ascending)

DataFrame sortByColumns(String[] columns, boolean[] ascending)
DataFrame sortByColumns(int[] columns, boolean[] ascending)
