AutoUpdatingBot - Adding intents through dialogue (Dialolgflow, node.js)

In this video we will create an auto-updating chatbot which will be self-expanding with new training phrases/responses (intents) through the dialog. The bot will be built on Dialogflow with a webhook written on node.js and hosted on Heroku.
