/**
* This class represents the Presenter (P) in the MVP pattern for constructing
* UI.
*
* The View represents some bag of element references and a definition of
* logical events sources by the View.
*
* The Model is not an explicit entity in this class hierarchy, and is simply a
* name used to refer to the instance state used by the Presenter. Concrete
* implementations may choose to abstract instance state behind an explicit
* Model class if they so choose.
*
* The View can be injected at any point in time.
*
* Presenters contain the logic for handling events sourced by the View,
* updating the Model, and for taking changes to the Model and propagating them
* to the View.
