// This header assigns a level implemenation trait to a collection type
// for all primitives.  It is needed so that archives which are meant to be
// portable don't write class information in the archive.  Since, not all
// compiles recognize the same set of primitive types, the possibility
// exists for archives to be non-portable if class information for primitive
// types is included.  This is addressed by the following macros.
