It looks like over-improved stout assumes smearing in all 4 dimensions. I guess to be even more forward thinking, we should just merge stout and over-improved stout to support 3-d and 4-d, as well as over-improved vs regular in general.
Ape smearing assumes spatial too. I like the orthogonal dimension method. Ping me when the PR is done.

Once PR #776 is in, the relevant comment is on line 47 of
include/kernels/gauge_stout.cuh
. A good way to address this might be similar to how Coulomb vs Landau gauge fixing is handled---pass in a dimension to not smear in (here, 3), or alternatively if 4 (or maybe we should use -1?) is passed in, do the full 4-d smearing. This is forward-thinking for evolution with smeared actions, where a full 4-d smearing is used, unlike in smearing for spectrum measurements.
