Goals for 0.2.0
---------------

X Drop support for Python <= 2.6
X Remove SQLParserError from top level module.
X Don't use 2to3 anymore
~ Remove unused code
~ Possible deprecation:
  - RightMarginFilter
    Seems to be broken and not used. However, a replacement would be good.
~ Update documentation
~ Cleanup docs on PyPI/github
~ Write release notes
