Question order within a topic should be randomized, and then cycled

No description provided.

A) Check if questions within the category and within the game are the same size (i.e. all questions have been asked on category)
A.1) If so, return a question within the game's question pool (still within the same category).
A.2) If no, randomize a unique question
A.3) Add new question to game's question pool
B) return the randomized question

or in Ruby:

  def new_question(category)

    # if no new question is available
    if Question.where(category: Question.categories[category]).count <= questions.where(category: Question.categories[category]).count
      question = questions.where(category: Question.categories[category]).sample
    else    
      question = loop do
        qq = Question::random_question(category)

        # prefer a unique question for our game
        break qq unless questions.include? qq
      end

      questions << question unless question.nil?
    end

    question
  end
