.. py:class:: ProblemInstanceController(problem_instance)

   Bases: :py:obj:`object`

   ``ProblemInstanceController`` decides whether to call problem
   controller or contest controller. Problem controller will be chosen
   if the problem instance is not attached to any contest (eg. for
   ``main_problem_instance``).

   Outside functions which want to call one of the above controllers
   and it is not clear that contest controller exists, should call
   ``ProblemInstanceController``, example::

       problem_instance.contest.controller.get_submissions_limit()  # WRONG
       problem_instance.controller.get_submissions_limit()  # GOOD

   From its functions the contest controller can call the problem
   controller, but the problem controller should not call the contest
   controller.

   For visuals::

       Call, for example *.get_submissions_limit()
                           |
                           V
              ProblemInstanceController
                |                    |
                V                    V
       ContestController  -->  ProblemController
