We'd gone to great effort when writing PresheafedSpace to create a coercion from morphisms of PresheafedSpaces to morphisms in Top.

It's hard to read, it's fragile.

So this PR rips out that coercion, and renames the "continuous map between base spaces" field from f to base, and uses that throughout.


Blocked on #3506, don't bother reviewing until that's settled.

I don't know anything about this but it looks innocuous enough and I trust Scott's judgment here. If nobody else chimes in in a bit I'll merge. @jcommelin @rwbarton is this one of your areas?

…n fancy coercion (#3507)

We'd gone to great effort when writing `PresheafedSpace` to create a coercion from morphisms of `PresheafedSpace`s to morphisms in `Top`.

It's hard to read, it's fragile.

So this PR rips out that coercion, and renames the "continuous map between base spaces" field from `f` to `base`, and uses that throughout.
