// Original design developed by Darin Adler based on classes developed by Mark
// Borgerding. Four original class templates were combined into a single endian
// class template by Beman Dawes, who also added the unrolled_byte_loops sign
// partial specialization to correctly extend the sign when cover integer size
// differs from endian representation size.
// TODO: When a compiler supporting constexpr becomes available, try possible uses.
