/**
 * This template simplifies generation of simple classes that wrap an id
 * in a typesafe way. Namely, you can use it to create a very lightweight
 * type that only offers equality comparators and hashing. Example:
 *
 *   struct MyIdType final : IdWrapper<MyIdType, uint32_t> {
 *     constexpr explicit MyIdType(uint32_t id): IdWrapper(id) {}
 *   };
 *
 * Then in the global top level namespace:
 *
 *   C10_DEFINE_HASH_FOR_IDWRAPPER(MyIdType);
 *
 * That's it - equality operators and hash functions are automatically defined
 * for you, given the underlying type supports it.
