/**
 `RLMAsymmetricObject` is a base class used to define asymmetric Realm objects.

 Asymmetric objects can only be created using the `createInRealm:`
 function, and cannot be added, removed or queried.
 When created, asymmetric objects will be synced unidirectionally to the MongoDB
 database and cannot be accessed locally.

 Linking an asymmetric object within an `Object` is not allowed and will throw an error.

 The property types supported on `RLMAsymmetricObject` are the same as for `RLMObject`,
 except for that asymmetric objects can only link to embedded objects, so `RLMObject`
 and `RLMArray<RLMObject>` properties are not supported (`RLMEmbeddedObject` and
 `RLMArray<RLEmbeddedObject>` *are*).
