Subject: MAINT: disable __array_function__ dispatch unless environment
 variable set

Per discussion on the mailing list, __array_function__ isn't quite ready to
release as part of NumPy 1.16:
https://mail.python.org/pipermail/numpy-discussion/2018-November/078949.html

We'd like to improve performance a bit, and it will be easier to support
introspection on NumPy functions if we support Python 3 only.

So for now, you need to set the environment variable
``NUMPY_EXPERIMENTAL_ARRAY_FUNCTION=1`` to enable dispatching.
