title: Dialogflow information/analytics retrieval and feed back to user
body: <p>I am just starting to use dialogflow. 
  I am wondering if I can retrieve information back to the user (analytics)?</p>
  
  <p>Say a user asks the chatbot "how long have I spent time with you?" or after a few quizzes, the user asks "what is my score"?
  The chatbot is being able to tell the user regarding the information.</p>
  
  <p>If so, is it able to do it via the console or needs to code in local?</p>
  
  <p>Thanks</p>
