[FLOW3-general] FLOW3 objects and JSON

[Zachary Davis, Cast Iron Coding LLC]

I've noticed that when I encode my model objects using json_encode, the 
object properties are stored in "FLOW3_Persistence_cleanProperties". Is 
there a good way to prepare an object for JSON encoding in such a way 
that only its public properties are accessible? Do I need to write a 
service for this, or is there something already present in FLOW3 that 
can help with this?
