  /**
   RLMValue is a property type which represents a polymorphic Realm value. This is similar to the usage of
   `AnyObject` / `Any` in Swift.
  ```
   // A property on `MyObject`
   @property (nonatomic) id<RLMValue> myAnyValue;
  
   // A property on `AnotherObject`
   @property (nonatomic) id<RLMValue> myAnyValue;
  
   MyObject *myObject = [MyObject createInRealm:realm withValue:@[]];
   myObject.myAnyValue = @1234; // underlying type is NSNumber.
   myObject.myAnyValue = @"hello"; // underlying type is NSString.
   AnotherObject *anotherObject = [AnotherObject createInRealm:realm withValue:@[]];
   myObject.myAnyValue = anotherObject; // underlying type is RLMObject.
  ```
   The following types conform to RLMValue:
  
   `NSData`
   `NSDate`
   `NSNull`
   `NSNumber`
   `NSUUID`
   `NSString`
   `RLMObject
   `RLMObjectId`
   `RLMDecimal128`
