a618bd7d6c refactor(library): use type classes for encoding all arithmetic operations
Before this commit we were using overloading for concrete structures and
type classes for abstract ones.

This is the first of series of commits that implement this modification

4a36f843f7 refactor(library/algebra/group_power,library/*): change definition of pow
I changed the definition of pow so that a^(succ n) reduces to a * a^n rather than a^n * a.

This has the nice effect that on nat and int, where multiplication is defined by recursion on the right,
a^1 reduces to a, and a^2 reduces to a * a.

The change was a pain in the neck, and in retrospect maybe not worth it, but oh, well.

version. The proofs are erased to minimize the size of the file that

This commit also removes the fake_simplifier. It doesn't work anymore
because simp is now a reserved word.
