Test extension array for storing nested data in a pandas container.

The JSONArray stores lists of dictionaries. The storage mechanism is a list,
not an ndarray.

Note
----
We currently store lists of UserDicts. Pandas has a few places
internally that specifically check for dicts, and does non-scalar things
in that case. We *want* the dictionaries to be treated as scalars, so we
hack around pandas by using UserDicts.
