Add complex field types Object, Array, SubModel and [SubModel] to Models (to be ignored in Grids)
You can (sort of) get Object and Array by not defining a type on model field definitions but explicit types would be better to be enforced. Also grids could ignore these types unless a custom editor is provided.

There is also a need for fields that reference submodels and arrays of submodels. HierarchicalDataSources do not really fit the requirement. See how mongoose (for mongoDB) handles documents and subdocuments.
