Scheduler admin tools

[pcantrell]

This is some work I hacked together locally for last year’s scheduling, rebased and tidied up a little.

It’s all under the general theme of giving more fine-grained control over the scheduling. Features include:

• Adds the ability to import/export schedules, so that an admin can run the annealer on a local machine (which is cheaper and far faster than running it on Heroku) and upload the results.
• Allows incremental scheduling, primarily to support scheduling additional sessions after the scheduler has already run.
• Provides a hacked-up but workable rake UI for restricting specific presenter / timeslot combinations, e.g. “Sally can’t present after 2:00”. (My fee for the pro bono work on the scheduler is that I get to use this feature to prevent myself from having to present in the first timeslot.)
• Improved stats on the scheduler’s results.

Sorry to submit this all as a big blob, but that’s how it ended up in the heat of last year.

Coverage remained the same at 92.523% when pulling ac0e65b96f8e5fe447839ef530907c17d1ab1815 on scheduler-admin-tools into 6ab940ddc4b9c3d8c309eec0ba660514f89cef48 on master.

@pcantrell thanks for this. As always your work is awesome and appreciated.

If you can find the time down the road I'd love a few more details (comments maybe) about what each of these variables mean and why ... specifically about things like opening_count room_size small_slots big_slots and what a best_possible_score actually means.

Thanks!

Thanks for wading through it. Agreed, much more documenting & clarifying needed. Assigned myself an issue so I don’t forget.
