/**
 * 
 * This interface must be implemented by classes who implement a strategy for changing the diagram model. 
 * Doing this through an interface allows interchangeability of strategies. 
 * This comes handy for eventual further implementations of a network-based real time sharing system. So 
 * the network client can implement this interface and, instead of directly changing the diagram, it can send 
 * messages to a server and change it accordingly to the server reply.
 * All in a transparent way to the classes which are in charge of editing the diagram.
