Typedefs
template<typename T >
using	osvr::common::detail::IsByteSwapperUnspecialized = std::integral_constant< bool, std::is_base_of< UnspecializedByteSwapBase, T >::value >
	Trait: For a given T=ByteSwap<ValueType> struct, is ByteSwap<ValueType> default/unspecialized?
template<typename T >
using	osvr::common::detail::IsByteSwapperSpecialized = std::integral_constant< bool,!IsByteSwapperUnspecialized< T >::value >
	Trait: For a given T=ByteSwap<ValueType> struct, is ByteSwap<ValueType> specialized?

Functions
template<typename T >
T	osvr::common::detail::genericByteSwap (T const v)
	Universal byte-swap function that always works, but isn't necessarily optimized.
template<typename T >
T	osvr::common::detail::integerByteSwapImpl (T const v, typename std::enable_if< IntegerByteSwapTraits< T >::HAVE_BYTESWAPPER >::type *=nullptr)
	Implementation of integerByteSwap(): Gets called when we have an exact match to an explicit specialization.
template<typename T >
T	osvr::common::detail::integerByteSwapImpl (T const v, typename std::enable_if< (!IntegerByteSwapTraits< T >::HAVE_BYTESWAPPER)&&(IntegerByteSwapTraits< T >::HAVE_OPPPOSITEBYTESWAPPER)>::type *=nullptr)
	Implementation of integerByteSwap(): Gets called when we do not have an exact match to an explicit specialization, but we do have a match if we switch the signedness.
template<typename T >
T	osvr::common::detail::integerByteSwapImpl (T const v, typename std::enable_if< (!IntegerByteSwapTraits< T >::HAVE_BYTESWAPPER)&&(!IntegerByteSwapTraits< T >::HAVE_OPPPOSITEBYTESWAPPER)>::type *=nullptr)
	Implementation of integerByteSwap(): Gets called if no explicit specialization exists (for the type or its opposite-signedness relative)
template<typename Type >
Type	osvr::common::integerByteSwap (Type const v)
	Swap the order of bytes of an arbitrary integer type.
