joel_osc's sandbox: Quiz Dependency

This module is an addon to the Quiz module which adds the concept of dependency to quizzes. The module adds an entity reference (node) field and a dependency type field to a quiz node so that the availability of one quiz can depend on the outcome (completed, passed, failed) of a another quiz. Thus chains can be set up so that a user/student must complete one quiz before moving on to the next.

This module relies on a patch to the quiz.module which added a hook to quiz_availability(). This patch is available in this moduled directory, but will need to be copied to the quiz module directory and then applied.

This module currently only supports one dependency - the future plan is to create the "dependent node" and "dependency type" fields as a field collection with unlimited entries so that multiple dependencies may be set on a single quiz.
