    Combined continuators - logical AND:
  Continues until one of the embedded continuators says halt!

20/11/00 MS: Changed the 2-continuator construct to a std::vector<eoContinue<EOT> >
             to be consistent with other Combined constructs
             and allow to easily handle more than 2 continuators
