(mvc) improve API for array type model objects
Integrate uuid generation into the core of the model system so items are uniquely identified and can be directly accessed using their uuids.
For example:
// set recurring pipe item to 1001
$model->setNodeByReference('pipes.pipe.86f19d48-bc91-4c70-a81c-e05cdd3a4372.queue', "1001");
// echo the contents back
echo $model->getNodeByReference('pipes.pipe.86f19d48-bc91-4c70-a81c-e05cdd3a4372.queue');
