Brownie

-----------

- Added :class:`brownie.datastructures.SetQueue`.

-----

- Expose wrapper for :func:`multiprocessing.cpu_count` instead the
function itself which was sometimes exposed as
:func:`brownie.parallel.get_cpu_count` because the latter is supposed
to have a `default` parameter which :func:`multiprocessing.cpu_count`
does not.

-----

- Switched theme to minimalism.
- Fixed wrong use of :rst:role:`meth` in the documentation of
:class:`brownie.abstract.AbstractClassMeta`.
- Added example to :class:`brownie.abstract.VirtualSubclassMeta`.
- Added example to :class:`brownie.abstract.AbstractClassMeta`.

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

Added Modules
- :mod:`brownie.importing`
- :mod:`brownie.abstract`

Added Classes
- :class:`brownie.itools.chain`
- :class:`brownie.datastructures.OrderedSet`
- :class:`brownie.datastructures.CombinedDict`.
- :class:`brownie.datastructures.CombinedMultiDict`.
- :class:`brownie.datastructures.ImmutableOrderedDict`.

- Make type checks work for dictionaries based on interfaces and
behaviour.

-----

- Fixed a :exc:`KeyError` and a :exc:`ValueError` which could occur
by calling :func:`brownie.parallel.get_cpu_count` on Windows or Linux
respectively.
