Add a config file for Travis-CI.
Separate pip installations onto separate lines.
Try to install openmpi with apt on travis-ci.
Fix `before_install` section, hopefully.
See if we can find mpicc.
Add MPE installation.
Add openmpi-bin to travis-ci package dependencies.
Add dependency on `six`.
Add explicit zmq installation on Travis-CI.
Fix  dependency.
Add a script to bring up an ipcluster before testing.
Add numpy dependency back.
Add a `time.sleep`...

until I can figure out how to poll to see if engines have started successfully.
Try installing zmq with apt to speed up build.

Also, split up pip installs onto different lines again (makes output better in Travis-CI).
Don't install `libzmq1` through `apt`.

It fails for some reason, and it's not strictly necessary.
Use `easy_install` for `pyzmq`.

`easy_install` is supposed to be faster for `pyzmq` since it can use eggs.
Go back to pip for `pyzmq`.
Run `nosetests` with the `-v` option.
Add the Travis-CI badge to the README.
Fix badge image.
