symphony-metronome 0.3.0

Metronome is a scheduler and task runner. It can be used locally as a cron replacement, or as a network-wide job executor. Events are stored via simple database rows, and optionally managed via AMQP events. Interval/time values are expressed with reasonably intuitive English phrases, ie.: 'at 2pm', or 'Starting in 20 minutes, run every 10 seconds and then finish in 2 days'.
