Parent Lookup in JSON API - Feature Request

[tylerm007]

JSON API can include parent lookups - this can be a big performance improvement using ListPicker since the API entity response will include the parent foreign key values (used in cache) - if there are multiple parents - use a comma separated value. The Yaml has the parent informant manytoone and can be included in the page generation. Need a specification or field name.
