Preparing for a new release (with Python 3 support)

[bbayles]

Greetings! I have joined this project as a maintainer (many thanks, @dw). Here is what I've been working on so far.

The big change is the addition of Python 3 support. With the help of six, this library now runs on both Python 2 and Python 3.

The other big change is to the organization of the files in the repo. I've created a traditional package structure, which makes for easier installation and testing.

In addition, I've updated setup.py to use setuptools, added the cdbmake.py script to the package installation, and updated the README with some documentation.

---

I'll start filing some issues and opening PRs for these items, but here's a preview of the plan:

• Release a new version with Python 3 support to PyPI
• Add CI testing of commits (with Travis)
• Add code coverage testing (with coveralls)
• Create a nicer interface for storing non-bytes data on Python 3
• Add a context manager for the Writer classes
• Add more thorough documentation (to ReadTheDocs)
• ...and a few more things.

I'll read through this PR and merge this soon to get started.

This all looks great, with one exception - test_ prefix on the filenames. It breaks tab completion and drives me insane :) Other than that please feel free to merge

Hmm, OK. I changed the test file's name.

Note that the test*.py file name pattern is needed for the python -m unittest discover function to work (see here), but python setup.py test still works. (python -m unittest discover -p "*_test.py" works also)

Thanks a ton!

Thank you! I'll ping you about making a release on PyPI after I check a few more things out with Python 3.

I pushed a commit to port _djb_hash to 3.x, I left the opt-in in place since the name of the package after all is "pure" :)

Ha, that was one of the things I was going to bring up gently a little later.
