+/// SerializeTrait - SerializeTrait bridges between the Serializer/Deserializer
+/// and the functions that serialize objects of specific types. The default
+/// 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).
