Post talk attendee surveys

Feedback from a user:

As a session ends, I would like for there to be some sort of pop-up on the attendee's screen to survey them about the session to get their immediate feedback, while they are here and engaged (rather than sending them an email after-the-fact).

I would like to be able to create multiple questions with different types of submissions (e.g. text responses, "rating from 1-10", and yes/no).

I would also like if HeySummit were able to take the aggregate responses to the questions, in particular the "rate from 1-10" and come up with mean/median for the responses so that we can best evaluate all the feedback received.
