Release 1.0.1

Bump the version number for release

Drop Python 2.6 support

Python 2.6 is rather old; this drops support for it entirely.  In
particular, this means we can now drop the dependency on argparse, as
argparse is in the standard library in Python 2.7 and Python 3.3 and
above.

Bump the version number for release

There's more that needs to be done here, and the ability to decorate
classes needs to be documented, but it's been a while since the last
release, and it would be nice to update the home page link.
