       This abstract base class represents just an interface which needs to be implemented by custom schedulers
       for controlling the execution of jobs in a Event::ExecFlow::Group which has the parallel option set.

       Event::ExecFlow ships a very simple example for a scheduler which just limits the maximum number of
       parallel executed jobs: Event::ExecFlow::Scheduler::SimpleMax.
