>From the examples that I tried out np.sort, sorts each column
separately (with axis = 0). If the elements of a row is supposed to
stay together, then np.sort doesn't work
>>> arr
array([[ 1, 14],
[ 4, 12],
[ 3, 11],
[ 2, 14]])
>>> np.sort(arr,axis=0)
array([[ 1, 11],
[ 2, 12],
[ 3, 14],
[ 4, 14]])
