feat(frontends/lean): add command #congr_rel for testing new congruence lemma for equivalence relations 2015-11-17 23:43:10 +00:00			`import data.list`
			`open perm`

			`#congr_rel @eq`
			`#congr_rel @iff`
			`#congr_rel @perm`
fix(library/app_builder): mk_rel supports relations where the lhs and rhs are not necessarily the last two arguments (e.g., heq) 2015-11-17 23:51:12 +00:00			`#congr_rel @heq`
