 * \brief C++ API: "Smart pointers" for use with and in ICU4C C++ code.
 *
 * These classes are inspired by
 * - std::auto_ptr
 * - boost::scoped_ptr & boost::scoped_array
 * - Taligent Safe Pointers (TOnlyPointerTo)
 *
 * but none of those provide for all of the goals for ICU smart pointers:
 * - Smart pointer owns the object and releases it when it goes out of scope.
 * - No transfer of ownership via copy/assignment to reduce misuse. Simpler & more robust.
 * - ICU-compatible: No exceptions.
 * - Need to be able to orphan/release the pointer and its ownership.
 * - Need variants for normal C++ object pointers, C++ arrays, and ICU C service objects.
 *
 * For details see http://site.icu-project.org/design/cpp/scoped_ptr

 * Destructor and adoptInstead().
 *
 * There is no operator T *() provided because the programmer must decide
 * whether to use getAlias() (without transfer of ownership) or orphan()
 * (with transfer of ownership and NULLing of the pointer).
