Define the Models for implementing Quizzes (collections of Questions) and their
Responses (collections of Answers to those Questions). These Models would
form the basis of storage for such items as:
Terms of Service (Quiz)
Question ("I agree...")
Response -> Answer (answer to "I agree..." confirmation)
solution ("Yes" Answer to the "I agree..." Question)
Mentor and Student surveys (Quiz)
Questions (including "Pay this student?")
Response -> Answers
solution ("Yes" Answer to the "Pay this student?" Question)
Organization applications
Student Proposal review, comment, and scoring system
GHOP task tracking (a specific task list item would be a Quiz)

Response entity participates in these relationships:
