      Typical structure used by many data types in RenderWare binary
      stream. Substream contains a list of binary stream entries,
      first entry always has type "struct" and carries some specific
      binary data it in, determined by the type of parent. All other
      entries, beside the first one, are normal, self-describing
      records.
