Having mesh files in the example be downloaded as a part of building the docs is surprising

[KristofferC]

I was wondering how the heck

Ferrite.jl/docs/src/literate-tutorials/porous_media.jl

Line 253 in f7f2592

grid = get_ferrite_grid(joinpath(@__DIR__, "porous_media_0p25.inp"))

was working when I couldn't find a reference to it in the repo or anywhere.

In my opinion it is better to download it as a part of the example so that you can just include the file. As it is right now, how are you supposed to know where the file is even coming from?
