renamed low-level "set_simps" and "set_induct" to have "ctor" or "dtor" in the name

renamed "map_simps" to "{c,d}tor_maps"

took out accidentally submitted "tracing" calls

fixed bug in "fold" tactic with nested products (beyond the sum of product corresponding to constructors)

simplified fact policies

generate "rel_as_srel" and "rel_flip" properties

started work on generation of "rel" theorems

make smlnj happy

more strict typscheme_equiv check: must fix variables of more specific type; dropped dead code; tuned order

cache should not contain material from descendant theory

some PIDE NEWS from this summer;

tuned whitespace;

tuned;

tuned proofs;

report proper binding positions only -- avoid swamping document model with unspecific information;

accumulate under exec_id as well;

more restrictive pattern, to avoid malformed positions intruding the command range (cf. d7a1973b063c);

misc tuning;

Thy_Syntax.consolidate_spans is subject to editor_reparse_limit, for improved experience of unbalanced comments etc.;

tuned signature;

tuned proofs;

misc tuning;

tighten margin for TextArea instead of Lobo;

misc tuning;

renamed LFP low-level rel property to have ctor not dtor in its name

changed base session for "HOL-BNF" for faster building in the typical case

renamed "rel_simp" to "dtor_rel" and similarly for "srel"

fixed a few names that escaped the renaming

tuned whitespace
