    MDL-74752 question regrading: implement the required hooks · 39abc011
    Tim Hunt authored
    This commit implements the necessary core hooks to ensure we only
    allow a regrade of a quetion attempt to take place if the new and old
    versions of the question are sufficiently similar.
    
    It will be followed by commits to each question type where the
    new method needs to be implemented.
    
    Automated tests will be included in the first of those (mulitple choice)
    becuse we need a question type that implements the hooks to test
    the core changes.
