py-xexpr

With lots of help from Pete Markowsky, and last-minute checking by Matt Horan, I released into the wild the Python X-expression library (py-xexpr). It's even on PyPI.

The license is LGPL, and there are only two public functions provided. The data structure was changed at the last minute to be more rigorous. The XML -> Xexpr function takes an optional argument telling it to strip whitespace. And there are many tests.
