Version 5.

Version 4.

Changes in this version include:
- Now we represent patch operations with special Python objects, rather than as
  generic tuples of goo. This gives us a place to put polymorphic methods like
  "how many bytes of the target does this operation encode".
- Implemented a much better diff algorithm, competitive with Xdelta in the size
  of the resulting patches, if not encoding time.

Version 2

Fill out the rest of the details in setup.py now that we have an actual
release.
