/*
* @brief The 'QmitkSynchronizedNodeSelectionWidget' implements the 'QmitkAbstractNodeSelectionWidget'
*        by providing a table view, using a 'QmitkRenderWindowDataNodeTableModel' and extending it
*        with base renderer-specific functionality.
* 
*        Given a base renderer, the selection widget is able to display and access render window specific properties
*        of the selected nodes. It can be connected with other QmitkSynchronizedNodeSelectionWidgets to synchronize
*        their state.
*        The widget can be used to decide if all data nodes of the data storage should be selected or
*        only an individually selected set of nodes, defined by a 'QmitkNodeSelectionDialog'.
*        If individual nodes are selected / removed from the selection, the widget can inform other
*        'QmitkSynchronizedNodeSelectionWidget' about the current selection, if desired.
*        Additionally the widget allows to reinitialize the corresponding base renderer with a specific
*        data node geometry.
