Nested object validation using ajv

[rwblair]

example: schema.metadata.StimulusPresentation

Do we add recommended_fields to the json schema language? Or call validation multiple times swapping out required entry in json schema between required_fields and recomended_fields and adjust severity accordingly.

I vote for this approach. I think you only need two passes, since the first one will catch required fields at any level. You might need to drop additionalProperties for the second pass, but I haven't thought that all the way through.
