Augmented Reality

Package rex provides a library for accessing the REX API. REX is a cloud-based operating system for building augmented reality applications. The first thing you have to do is to register at https://rex.robotic-eyes.com for a free REX account. Once you activated your account, you can simply create an API access token with a `ClientId` and a `ClientSecret`. This that information in your pocket, you can start building your REX-enabled application. An example application is called rx (https://github.com/breiting/rx) which is a command line tool accessing the REX system.
