9bedbbb739 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).

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

Now, even if the user opens the namespaces in the "wrong" order, the
notation + coercions will behave as expected.

After this commit, the bundled instances do not participate in the
class/instance resolution if we do not import algebra.bundled.
