=head1 NAME
Event::ExecFlow::Scheduler - Abstract class for parallel scheduling
=head1 SYNOPSIS
#-- Create a new Scheduler object
my $scheduler = Event::ExecFlow::Scheduler::XYZ->new ( ... );
#-- Attach scheduler to a group job with parallel execution
$group_job->set_parallel(1);
$group_job->set_scheduler($scheduler);
#-- The following methods gets called by Event::ExecFlow
#-- at runtime
$scheduler->schedule_job($job);
$scheduler->job_finished($job);
=head1 DESCRIPTION
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.
