/**
 * UClassID is used to identify classes without using the compiler's RTTI.
 * This was used before C++ compilers consistently supported RTTI.
 * ICU 4.6 requires compiler RTTI to be turned on.
 *
 * Each class hierarchy which needs
 * to implement polymorphic clone() or operator==() defines two methods,
 * described in detail below.  UClassID values can be compared using
 * operator==(). Nothing else should be done with them.
 *
 * \par
 * In class hierarchies that implement "poor man's RTTI",
 * each concrete subclass implements getDynamicClassID() in the same way:
 *
 * \code
 *      class Derived {
 *      public:
 *          virtual UClassID getDynamicClassID() const
 *            { return Derived::getStaticClassID(); }
 *      }
 * \endcode
 *
 * Each concrete class implements getStaticClassID() as well, which allows
 * clients to test for a specific type.
 *
 * \code
 *      class Derived {
 *      public:
 *          static UClassID U_EXPORT2 getStaticClassID();
