Instruct

-------------------

Release 2022-05-13

- Add dummy ``__iter__`` to ``SimpleBase`` which addresses principal of least astonishment for an empty class

-------------------

Release 2022-05-13

- Add ``devel`` to setup extras
- export ``clear``, ``reset_to_defaults``
- make ``_set_defaults`` first call the zero-init version, then cascade through the inheritance tree for any overrides
- add default functions for empty classes, use ``__public_class__`` for ``public_class`` calls
- Remove ``fast_new`` in favor of using ``_set_defaults``
- Allow ``__public_class__`` to be overridden in rare cases

-------------------

Release 2022-05-12

- Add change log
- Correct README example (it works!)
- Correct bug where ``_asdict``, ``_astuple``, ``_aslist`` were not added to an empty class
- Allow use of ``Annotation[type, ...others...]`` in type definitions
- Support use of ``Range`` in a type ``Annotation`` to restrict the range of values allowed for a type
- Support use of ``NoPickle``, ``NoJSON``, ``NoIterable`` to skip fields from pickling, JSON dumping and ``__iter__`` respectively
- ``_asdict``/``_astuple``/``_aslist`` will still return **ALL** values within an instruct-class.
- The field ``_annotated_metadata`` on a class contains a mapping of ``field_name -> (...others...)``
- Correct a bug where ``Literal[Enum.Value]`` would erroneously allow a matching non-Enum value if the ``__eq__`` on the Enum was overridden to allow it
- We now check via ``is`` and on ``__eq__`` checks we check the type as well to reject the wrong types
- Upgrade to Jinja2 for the 3.x series!
- Upgrade typing-extensions to 4.2.0
- Mark support as Python 3.7+
