ElementaryModel class abstract

The base class for an entity that contains a business logic required for a specific inheritor of ElementaryWidget.

You can implement this class freestyle. It may be a bunch of methods, streams or something else. Also it is not a mandatory for business logic to be implemented right inside the class, this model can be proxy for other responsible entities with business logic.

This class can take ErrorHandler as dependency for centralize handling error (for example logging). The handleError method can be used for it. When the handleError is called passed ErrorHandler handles exception. Also the WidgetModel is notified about this exception with WidgetModel.onErrorHandle method.
