Wed, 31 Oct 2007 12:19:43 +0100 chaieb changed signature according to normalizer_data.ML
Wed, 31 Oct 2007 12:19:41 +0100 chaieb tuned

Wed, 31 Oct 2007 12:19:35 +0100 chaieb (1) added axiom to ringb and theorems to enable algebra to prove the ideal membership problem; (2) Method algebra now calls algebra_tac which first tries to solve a universal formula, then in case of failure trie to solve the ideal membership problem (see HOL/Tools/Groebner_Basis/groebner.ML)
