3657d4c3ab feat(frontends/lean): coercion num -> int even when nat is not open, closes #219
I also had to mark the coercions as reducible.
Otherwise, given the constraint

          ?M (int.of_num 0) =?= (int.of_nat (nat.to_nat 0))

the unifier will not generate the solution

          ?M := fun x, x

3ca1264f61 refactor(library): mark 'decidable' theorems as definitions
If we don't do that, then any 'if' term that uses one of these theorems
will get "stuck". That is, the kernel will not be able to reduce them
because theorems are always opaque

3a95734fae feat(library): changes in eq.lean sigma.lean and category.lean
in eq.lean, make rec_on depend on the proof, and add congruence theorems for n-ary functions with n between 2 and 5
in sigma.lean, finish proving equality of triples
in category.lean, define the functor category, and make the proofs of the arrow and slice categories easier for the elaborator

in category, add Cat, slice, coslice, product and arrow categories, also add fully bundled approach
