Detailed Description

Class responsible for creating or building graphics objects. All objects are children of QGraphicsItem and ItemObserver. An object of a type is created from a coordinated. Also an object of a type can be built from the properties saved in a template. Only place where the model and the controller is instantiated and the MVC component is created.
