=head1 NAME
presque::ControlHandler
=head1 SYNOPSIS
# stop a queue
curl -X POST -H 'Content-Type: application/json' -d '{"status":"stop"}' http://localhost:5000/control/queuename
# start a queue
curl -X POST -H 'Content-Type: application/json' -d '{"status":"start"}' http://localhost:5000/control/queuename
# fetch the status of a queue
curl http://localhost:5000/control/queuename
=head1 DESCRIPTION
By default, when a queue is created, the status is set to 'open'. When a queue is set to 'stop', no job will be fetched from the queue, but it's still possible to add new jobs.
