Databox Custom Service Integration

Crashlytics, You rule!

We really love your service and this is why I wrote an integration that pushes data to [Databox](http://databox.com/) so we can monitor some of the stats from CL. At Databox we love stats.

Currently we are playing only with ```impacted_devices_count``` and ```crashes_count``` numbers. Do you have any plans for official API in the future?

I would like to have some feedback on this. Also, I didn't find any coding style rules so I used rubocop & reek. Hope you don't mind.
