/**
* The PlaceService class manages places in the application.
*
* A place is just the current state of the application which can be
* represented as an Object or a URL. For example, the place associated with:
*
* http://localhost:5000/map/6/2/17/ALL/terrain/loss
*
* Can also be represented like this:
*
* zoom - 6
* lat - 2
* lng - 17
* iso - ALL
* maptype - terrain
* baselayers - loss
*
* The PlaceService class handles the following use cases:
*
* 1) New route updates views
*
* The Router receives a new URL and all application views need to be updated
* with the state encoded in the URL.
*
* Here the router publishes the "Place/update" event passing in the route
* name and route parameters. The PlaceService handles the event by
* standardizing the route parameters and publishing them in a "Place/go"
* event. Any presenters listening to the event receives the updated
* application state and can update their views.
*
* 2) Updated view updates URL
*
* A View state changes (e.g., a new map zoom) and the URL needs to be
* updated, not only with its new state, but from the state of all views in
* the application that provide state for URLs.
*
* Here presenters publishe the "Place/register" event passing in a
* reference to themselves. The PlaceService subscribes to the
* "Place/register" event so that it can keep references to all presenters
* that provide state. Then the view publishes the "Place/update" event
* passing in a "go" parameter. If "go" is false, the PlaceService will
* update the URL. Otherwise it will publish the "Place/go" event which will
* notify all subscribed presenters.
*
* @return {PlaceService} The PlaceService class
