Moved well_ord_Memrel, lt_eq_pred, Ord_iso_implies_eq_lemma,
Ord_iso_implies_eq to top of file, as they do not require the other
material. Simplified proof of ordertype_subset.
Proved ordertype_eq: a short proof using deepen_tac! Deleted
bij_ordermap_vimage and ordermap_Memrel
"bij_ordermap_vimage and ordermap_Memrelf. [| f: bij(A,B); well_ord(B,r); x:A |] ==>\
\ ordermap(A,rvimage(A,f,r)) ` x = ordermap(B,r) ` (f`x)";
"\ ordermap(A,rvimage(A,f,r)) ` x = ordermap(B,r) ` (f`x)";i. [| Ord(i); j:i |] ==> ordermap(i,Memrel(i)) ` j = j"
because ordertype_eq serves the same purpose. Proofs of bij_ordertype_vimage
and ordertype_Memrel are now trivial.

lcp [Tue, 20 Dec 1994 10:21:32 +0100] rev 812
Simplified proof of ord_iso_image_pred using bij_inverse_ss.
Replaced not_well_ord_iso_pred_lemma by much simpler well_ord_iso_subset_lemma.
Simplifed proof of well_ord_iso_unique_lemma using well_ord_iso_subset_lemma.
