Dependency accessor for a whole testsuite.

Used in: a DEPENDS_ON(...) modifier for either a TEST(name, ...) or a TESTSUITE(name, ...).

Example: The test program

     
     #include <crpcut.hpp>
     
     TESTSUITE(partial)
     {
       TEST(success_by_nothing) { }
     
       TEST(fail) { FAIL << "oops"; }
     }
     
     TESTSUITE(full)
     {
       TEST(success_by_nothing) {}
     }
     
     TEST(failed_depend, DEPENDS_ON(ALL_TESTS(partial)))
     {
       // do nothing
     }
     
     TEST(successful_depend, DEPENDS_ON(ALL_TESTS(full)))
     {
       // do nothing
     }
     
     int main(int argc, char *argv[])
     {
       return crpcut::run(argc, argv);
     }

reports one test that has not run:
