title: How to 'exit' in the node.js version of Microsoft Bot Framework?
body: <p>I want to call the session.endDialog whenever the user inputs 'exit' as the message.</p>
  
  <p>Currently, my bot has many types of dialogues, but i want the bot to end the conversation when the 'exit' is typed by the user regardless of which dialogue the user is currently in. </p>
  
  <p>Is there a way to do this? </p>
