Implement a JFX controller for the creation and visualization of reference lists
In the SWT-based annotation table, support for creating reference lists to model elements existed. With the JFX-based annotation table, this way to specify relations between model elements in the GUI vanished.
To support the creation and visualization of such relations, a JFX-controller and GUI element shall be created that consists of a DynamicTreeViewer and corrsponding controls (Add/Remove/Up/Down buttons). Based on this abstract model specifications and maybe also annotation base classes should be created.
