Validating nested entities

[gxxcastillo]

How would we want to validate nested entities?

On .set():
This ones easy, just use the given validation method.

On .save():
This ones seems a bit trickier since we are saving the parent entity and don't have a direct reference to which sub-entity action to use. Would it be overly hacky to do something like

fields: [
   { "name": "address", "type": "entity", "action": "edit"}
]

Where address is a nested entity and the "action" is the name of the sub-entities action we want to use for validiting the given sub-entity.

I still haven't confronted this issue so I'm kinda taking a shot in the dark, however, .set() and .save() should be common use-cases.

So far, I've moved forward with the option to specify nested validation via an "entity" type on when saving.
