Merge pull request #11 from retr0h/retr0h/add-vagrantfile-provisioner

Configured Cassandra inside a Vagrant
Added tox and using a more pythonic directory tree

We should distribute this as a pip module.  Configured app to be packaged
as a bundle.  Also, added tox, which is great for testing.  Need to cleanup
module imports, and pep8 fixes.  However, will submit a new PR for those
cleanups.
