Smooth monoid

A smooth monoid is a monoid that is also a smooth manifold, in which multiplication is a smooth map of the product manifold G × G into G.

In this file we define the basic structures to talk about smooth monoids: SmoothMul and its additive counterpart SmoothAdd. These structures are general enough to also talk about smooth semigroups.

Basic hypothesis to talk about a smooth (Lie) additive monoid or a smooth additive semigroup. A smooth additive monoid over α, for example, is obtained by requiring both the instances AddMonoid α and SmoothAdd α.
