Can we also change some of those commit messages:

• operations: image: update setup.py -> operations: image: Add mahotas as dependency

• operations: image: Add a combine operation (temporarily) -> operations: image: Temporarily add a combine operation

  • Also, if you aren't using this operation within this PR, we shouldn't add it here. Let's add it once we're sure we're using it.

• df: base: Support default in create_definiton should be a part of the first commit, use fixup (f) to add the changes in that commit to the first commit: https://asciinema.org/a/342828

Also, if your updating resize here breaks the tutorial, then we need to update the tutorial in this PR. Ideally in the same commit as when it would break. I just modified it, so you'll need to rebase in the changes from master git fetch origin && git rebase origin/master

Seems to produce a formatting issue with pretty
