A BitField provides storage for a set a flags representing bits
import Foundation
/// A `BitField` is a struct that provides storage for a set a flags,
/// where each flag represents a bit either being set or not set (clear).
///
/// `BitField` is closely related to Swift's `OptionSet`, but it specializes
/// on treating bits as bits, rather than as abstract flags.
public struct BitField<T: UnsignedInteger> {
/// `naturalSize` represents the maximum number of bits that a `BitField` can hold, depending on the
/// size of the type over which it is generic.
