removed experimental Poplog/PML support;

removed obsolete ML_SUFFIX;

removed exotic 'token_translation' command;

proper name for LinearQuantifierElim;

removed old theorem database;

map_const: soft version, no failure here (recovers hiding of consts, because a hidden name is illegal and rejected later);

hide: delete all accesses from extra names -- reduces ambiguity in extern;

map_const: soft version, no failure here;

skolem_fact/thm: uniform numbering, even for singleton list; declare_skofuns: eliminated recovery via Clausify_failure -- should be sufficiently robust as is;

hide (open);

no_notation instead of hide;

* Recovered hiding of consts;

hide -> hide (open)

use regular error function;

add lemma finite_image_approx; remove unnecessary sort annotations

change orientation of fix_eqI and convert to rule_format; add lemma fix_ind2

export just one setup function; more antiquotations; to_nnf: import open, avoiding internal variables (bounds); ThmCache: added table of seen fact names; reorganized skolem_thm/skolem_fact/saturate_skolem_cache: maintain seen fact names, ensure idempotent operation for Theory.at_end; removed obsolete skolem attribute (NB: official fact name unavailable here);

removed obsolete skolem declarations -- done by Theory.at_end;
