Breaks on launching with "Flask run"

[e-Euler]

The purpose of this issue is to address the ability to port over to another flask application that I have been building. Currently if pyxtermjs is run with the following command the application works just fine.

python3 app.py

However when run under flask with the command "flask run" the application looses the interactivity with the shell session.

I am wondering why this is and how someone can go through and add/take-away from this base example to include it in an already existing flask application.

Issue addressed in FLASK_SOSCKETIO issue number #894 miguelgrinberg/Flask-SocketIO#894

Flask environments for whatever reason do not support websockets therefore needs the python environment in order to handle the websocket comms. pyxterm is not currently easily ported to already existing flask applications due to issues outside of pyxterm itself.
