/// behavior is to call static methods of the class for the object being
/// serialized, but this behavior can be changed by specializing this
/// template. Classes only need to implement the methods corresponding
/// to the serialization scheme they want to support. For example, "Read"
/// and "ReadVal" correspond to different deserialization schemes which make
/// sense for different types; a class need only implement one of them.
/// Serialization and deserialization of pointers are specially handled
/// by the Serializer and Deserializer using the EmitOwnedPtr, etc. methods.
/// To serialize the actual object referred to by a pointer, the class
/// of the object either must implement the methods called by the default
/// behavior of SerializeTrait, or specialize SerializeTrait. This latter
/// is useful when one cannot add methods to an existing class (for example).
