Bit operations for enum classs
Provides all kind of bit and comparison operators for an enum class E. Use like this: enum class MyEnum : unsigned { A = 1 << 0, B = 1 << 1, C = 1 << 2, }; template<> struct fe::is_bit_enum<MyEnum> : std::true_type {};
template<fe::BitEnum E>
constexpr auto	fe::to_underlying (E e) noexcept
