Fix default encoding problem in setup.py under Windows. Thank you @AlekseiCherkes for this fix!
Renaming assertXmlEquivalent to assertXmlEquivalentOutputs, and update documentation for clarity purpose. And up to 0.2.0.
Remove README.md version and rename README.txt → README.rst
(because it easier to maintain only one version :wink:)
Add syntax highlighting in README (works perfectly on PyPI, no worries)
Remove comment on test
Sort imports (see http://legacy.python.org/dev/peps/pep-0008/#imports)
Switch to setuptools and add lxml (3.3.6) as requirements
