Updated unit tests for new BPS_analytics script and bridge them w/ webapp

[jayunit100]

We've now completed #16, and the gh-pages code is live : We can visualize products.

A last minute change to the BPS Analytics script now needs to be tested in the java side of the code - maybe even we can bridge the test to the javascript, so that the test actually reads the same example input that the javascript app creates? not sure how to do that but would be awesome if we could :)

To be clear: We are talking about running the javascript in the gh-pages visualizer branch... inside of maven.

sure, we'll use node/browserify so we can run Javascript outside of the browser

What, specifically, do you want to test?
