 * Test for UObject, currently only the classID.
 *
 * Usage
 *   TESTCLASSID_NONE_DEFAULT(Foo)
 *      --  Foo is expected to not support "poor man's RTTI".
 *          Beginning with ICU 4.6, we only use compiler RTTI in new class hierarchies.
 *
 *   TESTCLASSID_NONE_CTOR(Foo, (1, 2, 3, status))
 *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_CTOR().
 *
 *   TESTCLASSID_NONE_FACTORY(Foo, (1, 2, 3, status))
 *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_FACTORY().
 *
 *   TESTCLASSID_ABSTRACT(Bar)
 *      --  Bar is expected to be abstract. Only the static ID will be tested.
 *
 *   TESTCLASSID_DEFAULT(Foo)
 *      --  Foo will be default-constructed.
 *
 *   TESTCLASSID_CTOR(Foo, (1, 2, 3, status))
 *      -- Second argument is (parenthesized) constructor argument.
 *          Will be called as:   new Foo ( 1, 2, 3, status)  [status is tested]
 *
 *   TESTCLASSID_FACTORY(Foo, fooCreateFunction(status) ) 
 *      -- call fooCreateFunction.  'status' will be tested & reset
 *
 *   TESTCLASSID_FACTORY_HIDDEN(class, factory)
 *      -- call factory.  Class is not available from a header.
 *      'status' will be tested & reset. This only tests uniqueness.
