Well-behaved class namespacing in Python. Inspired by https://erezsh.wordpress.com/2008/06/27/namespaces-lets-do-more-of-those-python-hackery/

Basic Usage
-----------

Example code::

    import class_namespaces as cn

    class MyCls(cn.Namespaceable):

        var = 1

        with cn.Namespace() as my_ns:
            var = 2

    assert MyCls.var == 1
    assert MyCls.my_ns.var == 2

Other things that work:

* Descriptors (methods, classmethods, staticmethods, properties, custom descriptors)
* super()
* Prepopulating Namespaces. The constructor takes the same arguments as a dict.
* abstractmethods. See the compat module.

Things that don't work:

* Various ways of putting a Namespace in a Namespace that I didn't see an obvious way to handle. In particular...

  * There is no way to put an established namespace directly into another namespace.
* Some pytest constructs behave weirdly inside the class definitions. Hopefully, this doesn't matter to anyone not writing tests for the package.
* No way to have instance Namespaces on non-hashable types, or subclasses of some built-in types, particularly tuple. Try using data descriptors instead.

Things that might work:

* New namespace features in Python 3.6. Current testing is spotty.
* Combining with other metaclasses. Unfortunately, the current setup is somewhat brittle. It may be necessary to experiment with the ordering of bases.
