refactor(library,hott): remove coercions between algebraic structures
...
They are classes, and mixing coercion with type class resolution is a
recipe for disaster (aka counterintuitive behavior).

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.
