f9874cd675 feat(library/tactic): add to_tactic_ext, it allows functions that return tactics to be used where a tactic is expected
For example, after this commit, we can write

simple_tac = REPEAT(ORELSE(imp_tactic, conj_tactic)) .. assumption_tactic

instead of

simple_tac = REPEAT(ORELSE(imp_tactic(), conj_tactic())) .. assumption_tactic()

c22f863114 refactor(library/tactic): improve solve method
Now, it produces the following outcomes:
1- A proof
2- A counterexample
3- A list of (unsolved) final states

Remark: the solve method does not check whether the proof or counterexample is correct.
