A table used to provide hints for proofs
Please see set-default-hints, see add-default-hints,
and see remove-default-hints for how to use this table. For
completeness, we mention here that under the hood, these events all update the
(table default-hints-table t '((computed-hint-1 clause) (computed-hint-2 clause stable-under-simplificationp)))
The use of default hints is explained elsewhere; see set-default-hints.
Advanced users only: see override-hints for an advanced variant of default hints.
