Revision 2998c271bc3a30c4c351c4d39943cf720390cad4 authored by Pierre-Yves Strub on 01 December 2015, 17:10:55 UTC, committed by Pierre-Yves Strub on 01 December 2015, 17:29:46 UTC 
Hint database for auto-exact.
 
Add a new hint mechanism for auto-applying lemmas. Lemmas are
added to the auto base with:

  `hint exact : L1 ... Ln.`

`trivial` (and all relatives) now tries to close any goal it is presented
by applying one of the lemmas of the database --- closing any generated
subgoal recursively. The lemmas in the hint database are not used
when `trivial` tries to close the subgoals.

Lemmas are applied using a rigid unification and with the view
mechanism disabled.

The current implementation is linear in the size of the database.
A pre-selection mechanism may be necessary in case the hint
database grows too much.
