This script performs density estimation for randomly generated data.
In contrast to "offline.py", it computes density progressively, using the
'run' method of PANENE.

To see the result, run this script with Python 3, Flask, and Flask-SocketIO
(we recommend to use Anaconda 3). Then, open 'localhost:8001' on your browser.
