+ * Implement the Serialize and Unserialize methods by delegating to a single templated
+ * static method that takes the to-be-(de)serialized object as a parameter. This approach
+ * has the advantage that the constness of the object becomes a template parameter, and
+ * thus allows a single implementation that sees the object as const for serializing
+ * and non-const for deserializing, without casts.
