/**
 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`
