```

specify the root or each_serializer option, or render a JSON String

For JSONAPI, `include_data` currently means, "should we populate the
'data'" key for this relationship. Current options are true/false.
This adds the `:if_sideloaded` option. This means "only
populate the 'data' key when we are sideloading this relationship." This
is because 'data' is often only relevant to sideloading, and causes a
database hit.
