Feature req: queries across multiple dates

[giacecco]

E.g. https://goingunderground.herokuapp.com/signals/train-speed/2016-02-01T23:59:00+00:00/2016-02-02T00:01:00+00:00.json gives an internal server error. The human version hangs.

When there is no data I get a valid json with no data.

Ah, that's expected behaviour. You can't currently query across days, as data for each day is stored in a separate index. This should fail in a slightly friendlier way though.

Ok not a big deal. There may be trains that travel at midnight though. The code we wrote is just for our own use or we have some commitment to share it back / publish it?
