## Problem

Alephant (and all its subsequent gems) doesn't demonstrate very well how it can be utilised.

## Solution

Lots of BBC projects are using Alephant by building applications around the Renderer/Broker pattern.

This PR aims to mimic that pattern with the help of [Spurious](https://github.com/stevenjack/spurious) and [Alephant-Harness](https://github.com/BBC-News/alephant-harness/)
