<p><strong>Chaplin.Dispatcher</strong> sits between the router and controllers to listen
for routing events. When they occur, Chaplin.Dispatcher loads the target
controller module and instantiates it before invoking the target action.
Any previously active controller is automatically disposed.</p>

<p><strong>Chaplin.Layout</strong> is the top-level application view. It <em>does not
inherit</em> from Chaplin.View but borrows some of its functionalities. It
is tied to the document dom element and registers application-wide
events, such as internal links. And mainly, when a new controller is
activated, Chaplin.Layout is responsible for changing the main view to
the view of the new controller.</p>

<p><strong>Chaplin.mediator</strong> is a singleton that serves as the sole communication
channel for all parts of the application. It should be sealed so that its
misuse as a kitchen sink is prohibited. If you do want to give modules
access to some shared resource, however, add it here before sealing the
mediator.</p>

<p><strong>Chaplin.Router</strong> is responsible for observing URL changes. The router
is a replacement for Backbone.Router and <em>does not inherit from it</em>
directly. It's a different implementation with several advantages over
the standard router provided by Backbone. The router is typically
