/**
 * 
 * The DiagramModelUpdater class is used to make changes to the diagram model. The reason why 
 * changes are not made directly to the model is allowing the network-local diagram interchangeability. 
 * A NetDiagram differs from a local 
 * diagram only by its DiagramModelUpdater implementation. The rest of the operations are 
 * performed through the delegate local diagram which is passed as argument to the constructor.    
 * In this way a local diagram can be easily turned into a network diagram and vice versa.
