  * A class to help manage a poll in a room.

  * A poll is made up of a start event that poses the question and possible answers,
  * and is followed by a series of response events as users in the room select
  * their choice. This purpose of the poll handler is to keep track of all this as
  * the poll is displayed as a single event in the timeline which merges all this
  * information.
