/**
 * This is a view controller for the first steps in the wizard. The "back" and "finish" buttons of the action-bar that
 * is shown on each view of the wizard are defined in the AbstractWizardController class. So this class only needs to
 * define the "next" button. Because this is the first step in the wizard the "back" button should never be used. When
 * looking in the fxml files of the wizard the action-bar that contains all buttons is defined as a global fxml. By
 * doing so a developer doesn't need to recreate it for each view. Therefore the "back", "next" "finish" button will
 * automatically appear on each view. Because the "back" button shouldn't be used here it will become disabled by
 * setting the disable property in the init() method of the controller. As described in tutorial 1 the init() method
 * is annotated with the  @PostConstruct annotation and therefore this method will be called once all fields of the
 * controller instance were injected. So when the view appears on screen the "back" button will be disabled.
 *
 * When looking at the @FXMLController annotation of the class you can find a new feature. next to the fxml files that
 * defines the view of the wizard step a "title" is added. This defines the title of the view. Because the wizard is
 * added to a Stage by using the Flow.startInStage() method the title of the flow is automatically bound to the window
 * title of the Stage. So whenever the view in the flow changes the title of the application window will change to the
 * defined title of the view. As you will learn in future tutorial you can easily change the title of a view in code.
 * In addition to the title other metadata like a icon can be defined for a view or flow.
