This is good for now. FYI, I'm starting to think the end result we want is for
the snooze annotations to be built in to the auto-sheriff data directly (i.e.
auto-sheriff would read the snooze data out of sheriff-o-matic's backend and
integrate the data into it's feed), i.e. it would just have the snooze
annotation as part of the entry in the range_groups field.

[dstockwell, 2014/08/11 01:20:42]

Why does sheriff-o-matic need its own backend? Can't we just store annotations
directly in auto-sheriff. I'm not seeing the difference between auto-sheriff and
sheriff-o-matic.

Very shortly, in the next day or two, we'll be getting rid of auto-sheriff and
sheriff-o-matic will be the data source. At this point, all auto-sheriff does is
host a json file. Confusingly, it doesn't even generate the json file.
