Added reference to Jeremy Dawson's paper on the word library.

Catch exceptions arising during the abstraction operation.
Filter out theorems that are "too deep".

chaieb [Wed, 31 Oct 2007 12:19:37 +0100] rev 25251
(1) signatures updated according to normalizer_data.ML (added field ideal in entry);
(2) For a theory the conversions returned are now ring_conv (as before, proves a universal statement), simple_ideal proves ideal membership for one polynomial ; multi_ideal solves the more general ideal membership for several existentially quantifier variables involved in several conjunctions; a simpset containing a simproc to turn x = y into p = 0 where p is the normal form of x - y;
(3) Added ideal_tac a tactic to prove general ideal membership (cf. John Harrision CADE 2007) ;
(4) Added algebra_tac : first tries ring_tac (old algebra) then ideal_tac
chaieb [Wed, 31 Oct 2007 12:19:35 +0100] rev 25250
(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)
chaieb [Wed, 31 Oct 2007 12:19:33 +0100] rev 25249
