App
An app is basically a controller application for one or more VibHub Devices. Such as a website or Second Life relay.
Generally, VibHub communication goes User Input -> App -> Server -> Device.
VibHub currently has two methods of interfacing an App with the server: REST and Websockets. Websockets is faster and generally the go-to. But if your application can't handle that, and you're fine with less frequent updates, the REST API is very easy to use!
