+/**
+ * The shared serialization delegate for this package.
+ *
+ * @implNote
+ * This class wraps the object being serialized, and takes a byte representing the type of the class to
+ * be serialized. This byte can also be used for versioning the serialization format. In this case another
+ * byte flag would be used in order to specify an alternative version of the type format.
+ * For example {@code LOCAL_DATE_TYPE_VERSION_2 = 21}.
+ * <p>
+ * In order to serialize the object it writes its byte and then calls back to the appropriate class where
+ * the serialization is performed. In order to deserialize the object it read in the type byte, switching
+ * in order to select which class to call back into.
+ * <p>
+ * The serialization format is determined on a per class basis. In the case of field based classes each
+ * of the fields is written out with an appropriate size format in descending order of the field's size. For
+ * example in the case of {@link LocalDate} year is written before month. Composite classes, such as
+ * {@link LocalDateTime} are serialized as one object.
+ * <p>
+ * This class is mutable and should be created once per serialization.
