How to test locally:

1. git clone https://github.com/paypal/NNAnalytics.git
2. (Temporary measure) Create a directory for NNA to use: mkdir /usr/local/nn-analytics.
3. Run the public static void main method in TestNNAnalytics.java under src/test/java.
4. A local instance of NNA should start and be accessible at http://localhost:4567.
