Update dependency on numba to <= 0.11.1, since we need closures which were removed for
0.12.
Add README.rst to MANIFEST.in since it is not automatically included like the old plain
README was.
Add setup.cfg to configure nosetests defaults for not capturing too much logging info
and creating html to show test coverage.
Add Makefile for common development tasks and add flake8 and pylint to devel
dependencies for code checking and analysis.
First attempt at .travis.yml to enable Travis CI testing through Github.
