Sheafed spaces #

Introduces the category of topological spaces equipped with a sheaf (taking values in an arbitrary target category C.)

We further describe how to apply functors and natural transformations to the values of the presheaves.

A SheafedSpace C is a topological space equipped with a sheaf of Cs.
