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() Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-11-29 17:39:31 +00:00			`Set: pp::colors`
