Still more work to do: about 14 failing tests and still need to wire up
the spec tests and README doctests.

Python 3.2 deprecates cgi.escape() and introduces the html module in its place.

The assertEquals() function is deperecated in Python 3.2:

Resolved issue #104.

Still need to get spec tests and README doctests working though.

Older versions of Python (2.5 and earlier?) apparently didn't allow keyword
arguments to follow positional arguments called with the * operator.

Running `python setup.py test` with Python 2.7 runs all tests except
for the spec tests and the doctests in the README file.
