At some point I'd like to expose an Enum to App Developers that they can use for comparison/equality, ie.
```js
this.currentLocation() === AppLocation.TICKET_SIDEBAR; // @returns true
AppLocation.get(this.currentLocation()); // @returns AppLocation.TICKET_SIDEBAR
AppLocation.TICKET_SIDEBAR.is(this.currentLocation()); // @returns true
```
We can add a story for that linked to the work James and I started on identifying an Enum library we could use, or even writing one.
