MVP pattern

MVP is Model - View - Presenter.

• Model is an interface defining the data to be displayed or otherwise acted upon in the user interface.
• View is a passive interface that displays data (the model) and routes user commands (events) to the presenter to act upon that data.
• Presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it for display in the view.
