Save data to HDF5ΒΆ

Save nddata to standard HDF5 format.

WARNING!!, attributes ['other_info'] are dictionaries!
WARNING!!, attributes ['dimlabels'] are lists!
You didn't set units for b before saving the data!!!
Units set for the a axis are: s
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])
                +/-None
        dimlabels=['a', 'b']
        axes={`a':array([0, 1, 2])

                `b':array([1, 2, 3])
