Streamification is coming

Streamified the things! Also changed the docs slightly. The build is currently failing because of a strange npm error in node 0.8. I'm not sure what to do about that -- all tests are passing...

I'm working on an example, hopefully going to hook it up to some d3 graphs at some point, and let the user click around and make some events. https://github.com/AWinterman/estate-example
