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.

Unused method argument - `params`. If it's necessary, use `_` or `_params` as an argument name to indicate that it won't be used. You can also write as `detonate(*)` if you want the method to accept any arguments but don't care about them.
