PLEASE NOTE: 
This application was created for demonstration purposes.  
Code is not production ready, and requires further testing and modification.

About this application:
The following application creates a websocket using node.js and 
listens for messages directed at the slack application/bot.  After a message
has been sent to the application, it is written to a textfile so that it can be 
processed by the admin_assistant.py script
