/*
 * Changes to AbstractSubpanelImplementation for DeployedSubpanels
 * The main differences are in the load and save of the definitions
 * For subpanels we must make use of the SubPanelDefinitions class to do this; this also means that the history mechanism,
 * which tracks files, not objects, needs us to create an intermediate file representation of the definition that it can manage and restore
