/**
* Runs a student's solution by invoking PHP via the `php-cgi` binary, populating all the super globals with
* the information from the request objects returned from the exercise. The exercise can return multiple
* requests so the solution will be invoked for however many requests there are.
*
* Running only runs the student's solution, the reference solution is not run and no verification is performed,
* the output of the student's solution is written directly to the output.
*
* Events dispatched (for each request):
*
* * cgi.run.student-execute.pre
* * cgi.run.student.executing
*
* @param string $fileName The absolute path to the student's solution.
* @param OutputInterface $output A wrapper around STDOUT.
* @return bool If the solution was successfully executed, eg. exit code was 0.
