added markup_cumulate operator;

depth-first proof forking for improved locality (wrt. cancellation and overall memory usage);

tuned;

more abstract Markup_Tree;

prefer statically typed Text.Markup;

discontinued entity text color, notably historic red for classes; tuned entity names;

more scalable Proof_Context.prepare_sorts; reverted a97251eea458 -- uniform position constraints independently of accidental source positions (e.g. TTY vs. document);

increasing values_timeout to avoid failures of isatest with HOL-IMP

renaming example invocations: tester predicate_compile is renamed to smart_exhaustive

adding CPS compilation to predicate compiler; removing function_flattening reference; new testers smart_exhaustive and smart_slow_exhaustive; renaming PredicateCompFuns to Predicate_Comp_Funs;

adding option allow_function_inversion to quickcheck options

more efficient prepare_sorts -- bypass encoded positions;

suppress irrelevant positions;

more generous margin;

pass term positions into check phase, where resulting types are reported accordingly, and eventually shown as tooltips;

tuned signature;

discontinued unused Thm.compress (again);

renewed prolog-quickcheck

adding some test cases for preprocessing and narrowing

adding a minimalistic preprocessing rewriting common boolean operators; tuned

merged

merged

tune post-processing of simproc-generated rules so they won't produce Numeral0 or Numeral1

use simproc_setup for some nat_numeral simprocs; add simproc tests

add ring_char_0 class constraints to several simprocs (internal proofs of #n ~= 0 fail for type s not in this class); test simprocs using most general type classes instead of just int and rat.

simultaneous check; tight maxidx;

avoid separate typ_check phases, integrate into main term_check 0 instead (cf. its Syntax.check_typs in Type_Infer_Context.prepare);

clarified singleton_fixate: intersection with supersort is identity, only replace actual type inference parameters; tuned reject_other, after_infer_fixate;
