Partial serialization or deserialization

[andreas-aeschlimann]

I encountered some use cases where partial serialization would have been useful.

For example, I get a User instance from the server and deserialize it. Then, a user updates some fields in a form and wants to save the form. The project serializes the form data to a User object (this.serialize(formData, User)), but it will throw an error because the User data is incomplete.

It would be nice if we could have a flag that allows skipping incomplete objects.
