[DesignPattern] MVP

Model-View-Presenter is a design pattern for separating the concerns of display and data.

• Model - The observable data model that is the subject of the user-story.
• Presenter - A construct that takes data from the model and exposes it to views.
  
• View - Shows the interaction and display surface of the application.

-> acts as an external mediator

	Model-View-Controller	Model-View- Presenter
	Application domain logic View	Application domain logic
	Receives model elements from controller. Displays and interacts with element. Controller	Receives data from presenter, notifies presenter of interactions.
	Supervises view/model, performs actions in response to events/changes.	Delegates events to model. Re-maps model outgoing events into state changes.

-> MVC: a view would receive an update and manipulate the model accordingly after being configured by its controller.
