Boost.Range support for ATL/WTL CString

#pragma once

// Note:
//   verify, whether debugging or not, throws an exception
//   that means exceptional runtime-error.
//   On the other hand, ATLASSERT checks "static" coding mistakes.
//   I think that it was right for ATL designers not to add ATLVERIFY
//   on the initial version, because it must be meaningless
//   to turn on detection of runtime-error that depend on environment
//   only when debugging.
//   Well, api failure is always runtime-error,
//   so you must use verify_api.
