 * \brief   The GuiView class
 * \details Global view which is used mostly for non-messaging purposes.
 *          Different purposes could be like device notifications and such.
 *          This class is a general purpose class which is registered in the QML Engine
 *          to be able to interact with the QML files and receives the user actions and passes them to the GuiController
 *          for evaluation and applies the navigation validation on the QML.
 * \note    This class should be used carefully since having a global purpose class can lead to having an entity
 *          which potentially contains unrelated logics.
