Ok, I've implemented the idea of the dict_factory, making sure to
implement all the methods required by IEnumerableMapping and
IReadMapping. All tests pass and it works in my specific end use-case.

However, since we can use the OrderedDict type in Python < 2.7 by means
of the ordereddict package, what do you think of making that the default
dict type and adding an 'ordereddict' dependency for older Python
versions? (Please see Charlie and my discussion about it.)

If we still use the concept of a dict_factory, it wouldn't make sense to
implement the OrderedDict specific methods like "popItem", but the
"keys" method would be ordered, which I think would be enough.
