// 4.1 Native Markup Request Object
//
// The Native Object defines the native advertising opportunity available for bid via this bid request.
// It will be included as a JSON-encoded string in the bid request’s imp.native field or as a direct JSON object, depending on the choice of the exchange.
// While OpenRTB 2.x officially supports only JSON-encoded strings, many exchanges have implemented a formal object.
// Check with your integration docs.
//
// Note: Prior to VERSION 1.1, the specification could be interpreted as requiring the native request to have a root node with a single field “native” that would contain the object above as its value.
// The Native Markup Request Object specified above is now the root object.
