%proving zero_set_within_complex

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
zero_set_within_complex:
(see dependencies)

zero_set_within_complex may now be readily provable (assuming required theorems are usable).  Simply execute "%qed".
