Unbundled monoid and group homomorphisms (deprecated)

This file defines typeclasses for unbundled monoid and group homomorphisms. Though these classes are deprecated, they are still widely used in mathlib, and probably will not go away before Lean 4 because Lean 3 often fails to coerce a bundled homomorphism to a function.

main definitions

monoid_hom, is_monoid_hom (deprecated), is_group_hom (deprecated)

implementation notes

There's a coercion from bundled homs to fun, and the canonical notation is to use the bundled hom as a function via this coercion.

There is no group_hom -- the idea is that monoid_hom is used. The constructor for monoid_hom needs a proof of map_one as well as map_mul; a separate constructor monoid_hom.mk' will construct group homs (i.e. monoid homs between groups) given only a proof that multiplication is preserved,

Throughout the monoid_hom section implicit {} brackets are often used instead of type class [] brackets. This is done when the instances can be inferred because they are implicit arguments to the type monoid_hom. When they can be inferred from the type it is faster to use this method than to use type class inference.
