tactical CHANGED now uses alpha-eta conversion, not alpha conversion Streamlined code

Renamed subset_Sigma_llist to subset_Times_llist

new theorems about diag

At last: linear arithmetic for nat!

Replaced the puny nat_transitive.ML by the general fast_lin_arith.ML.

fixed a link

added Real/Hyperreal

Addition of Hyperreal theories Zorn and Filter

moved diag (diagonal relation) from Univ to Relation

tidied up list definitions, using type 'a option instead of unit + 'a, also using real typedefs instead of faking them with extra rules

tuning to assimiliate it with PhD;

Added a general refutation tactic which works by putting things into nnf first.

Added filter_prems_tac

removed prs / prs_fn;

guarantees laws

simplified ensures_UNIV

new thms for invariant

new theorem program_equalityE

renamed vars

image_id in simpset

removed prs / prs_fn (broken, because it did not include \n in its semantics, forcing writeln to add one uncoditionally); replaced prs_fn by writeln fn;

added undos, redos;

tty: issue wakeup;

std_output, prefix_lines;

better miniscoping rules: the premise C~={} is not good because Safe_tac eliminates such assumptions.

fixed method syntax;

break: exhibit state stack;
