class_docstr: Simple interactive world involving just two agents talking.
  
  In more sophisticated worlds the environment could supply information, e.g. in
  tasks/convai2 both agents are given personas, so a world class should be written
  especially for those cases for given tasks.
docstr: Override to return a pair of contexts with which to seed the episode.
  
  This function will be called before the first turn of every episode.
