Add support for custom question types

[n1vedhar1]

#Add support for custom questions

#Approach

• Added custom_question_types accessor so that new questions can be added via initializer

#Usage

• Create a custom question model extending the existing type in app/models/rapidfire/question
  Eg:
  If we want to create a 'custom' question which behaves like short question

# app/models/rapidfire/questions/custom.rb
module Rapidfire
  module Questions
    class Custom < Rapidfire::Questions::Short
    end
  end
end

• Create a partial for that in app/views/rapidfire/answers

#app/views/rapidfire/answers/_custom.html.erb
<%= render partial: "rapidfire/answers/errors", locals: {answer: answer} %>
<div class="form-group">
  <%= f.label :answer_text, answer.question.question_text.html_safe %>
  <%= f.text_field :answer_text, value: answer.answer_text || answer.question.default_text, placeholder: answer.question.placeholder %>
</div>

• Add the created type in initializer file. (Create rapidfire.rb in app/config/initializers if not there)

# config/initializers/rapidfire.rb
Rapidfire.config do |config|
  config.custom_question_types = ["Rapidfire::Questions::Custom"]
end
