Continuous affine maps.

This file defines a type of bundled continuous affine maps.

Main definitions:

• ContinuousAffineMap

Notation:

We introduce the notation P →ᴬ[R] Q for ContinuousAffineMap R P Q (not to be confused with the notation A →A[R] B for ContinuousAlgHom). Note that this is parallel to the notation E →L[R] F for ContinuousLinearMap R E F.
