Imported overlord solution

Joe/Sophia,
I spent this morning re-doing my level_up fork and branches. I believe it is correct now. Each task now has its own branch containing nothing other than changes pertinent to the task itself.

I'm resubmitting a code-review pull-request for overlord.

Wording here is strange. Just say `9854 and 0941`. Even better if you specify which is which.
