LaterJob - A Database Queue with Metrics

I have in the past needed a simple queue for applications hosted on 'sharded host' or other limited php environments with:

no access to the cli,

no persistent processes

no chmod - physically set write permissions in cpanel or equivlent.

Small scale single node installations.

I developed LaterJob to power jobs such as:

1. Mail Queues.

2. Sms Queues.

3. Thumbnail Generation.

4. PDF Generation.

Its a simple queue, simlar to Zend\DB\Queue but comes packaged with metrics

* Written with Symfony2 components and Doctrine DBAL.

* Uses Cron scripts for workers and metric generation.

* Can Run many workers.

* Multiple queues per script if needed.

* Records state transitions into the database as activity which drive Metrics.

* Installed via composer.

* Restful Silex API to query monitor data
