blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42347
properly implemented definitional CNF for the new Skolemizer (and moved the code for the old Skolemizer -- tuning), removing big chunks for experimental/debugging code
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42346
remove experimental code added in 85bb6fbb8e6a
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42345
added examples of definitional CNF facts
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42344
"unify_first_prem_with_concl" (cf. 9ceb585c097a) sometimes throws an exception, but it is very rarely needed -- catch the exception for now
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42343
compile
blanchet [Thu, 14 Apr 2011 11:24:05 +0200] rev 42342
handle case where the same Skolem name is given different types in different subgoals in the new Skolemizer (this can happen if several type-instances of the same fact are needed by Metis, cf. example in "Clausify.thy") -- the solution reintroduces old code removed in a6725f293377
blanchet [Thu, 14 Apr 2011 11:24:04 +0200] rev 42341
removed obsolete Skolem counter in new Skolemizer
