'A JSON representation of the :class:`Dataset` object. If headers have been
set, a JSON list of objects will be returned. If no headers have
been set, a JSON list of lists (rows) will be returned instead.
A dataset object can also be imported by setting the :class:`Dataset.json` attribute: ::
data = tablib.Dataset()
data.json = \'[{age: 90, first_name: "John", liast_name: "Adams"}]\'
Import assumes (for now) that headers exist.'
