collections.abc isn't handled by install_aliases

[bhrutledge]

I want to do isinstance(obj, Iterable).

In Python 2: from collections import Iterable

In Python 3: from collections.abc import Iterable

But, collections.abc isn't part of future.standard_library.install_aliases. Could it be?

Not sure it's helpful, but there's an open PR to add it to six.moves: benjaminp/six#241

Here's another implementation:

After pip install jaraco.compat:

from py33compat.collections.abc import Iterable
