Add support for embedded types.
We now support embedded types in the sense of unwrapping nested objects into their parent Document to flatten out domain models where needed. A domain class of: public class User { @id private String userId; @Embedded(onEmpty = USE_NULL) private UserName name; } public class UserName { private String firstname; private String lastname; } renders: { "_id" : "1da2ba06-3ba7", "firstname" : "Emma", "lastname" : "Frost" } Resolves #2803. Original pull request: #896.
