Thm.proof_of returns proof_body;
adapted PThm;
wenzelm [Sat, 15 Nov 2008 21:31:25 +0100] rev 28804
refined notion of derivation, consiting of promises and proof_body;
removed oracle_of (would require detailed check wrt. promises);
proof_of returns proof_body;
wenzelm [Sat, 15 Nov 2008 21:31:23 +0100] rev 28803
reworked type proof: MinProof is vacous, added Promise, refined PThm (with serial);
added type proof_body, which covers oracles and thms of local proof;
added general fold_body_thms, fold_proof_atoms;
removed thms_of_proof, thms_of_proof', axms_of_proof;
slightly more abstract handling of body content (oracles, thms);
rewrite_proof: simplified simprocs (no name required);
thm_proof: lazy fulfillment of promises;
