How To Test:

1. git clone https://github.com/paypal/NNAnalytics.git
2. (Optional) Run ./gradlew -PmainClass=com.paypal.nnanalytics.TestNNAWithStreamEngine execute. This will run the public static void main method in com.paypal.nnanalytics.TestNNAWithStreamEngine.java under src/test/java. Use CTRL+C to stop the demo.
3. (Optional) Run ./gradlew -PmainClass=com.paypal.nnanalytics.TestWithMiniClusterWithStreamEngine execute. This will run the public static void main method in com.paypal.nnanalytics.TestWithMiniClusterWithStreamEngine.java under src/test/java. Use CTRL+C to stop the demo.
4. A local instance of NNA should start and be accessible at http://localhost:4567. Use a browser, preferably Chrome or Firefox, to view.

** The difference between (a) and (b) is that (a) will launch a static instance of NNA with an unchanging files and directories where as (b) will mimic a production cluster on your local machine and update NNA as it runs.
