Does it automatically pick everything to serialize?

How would you make it more selective?

struct Me
{
	int x;
	int y;
}

serialize x but not y.

Would you have to create a custom serializer?

If so I would like to see an example with the custom serializer and 
deserializer that only does the x.

There is no register serializer example.

I assume that the wrapper is the custom serializer that can be registered.

Then there is the toData that a struct can have, basically
member functions that do the serialization. Priority is
given to the registered serializer over the member functions.

And the last one. ObjectStructSerializerHelper is more a default
serializer if none is registered or doesn't have the correct
isSerializable member functions.
ObjectStructSerializerHelper(T) (T .....)
