Make the Python trees and sets accept an explicit None argument to indicate an open range in keys(), values() and min/maxKey(), as per the interface documentation and the C implementation. Except actually, the C implementation didn't accept a None for mim/maxKey, so make it actually do that.
One more test for set keys
Actually do what the comment says and make both bounds None.
Changelog for PR #3.
Normalize.
Note explicit support for Python 3.4.
