 * This command handler executes the model obfuscator in a way that only writable resources are modified in the resource
 * set of the editing domain provided by the editor.
 * 
 * <p/>The seed used for the obfuscator is displayed in a confirmation dialog and logged to the Eclips logger with Info
 * level.
 * 
 * <p/>The obfuscation is performed with a {@link SimpleEMFModelObfuscator} in an EMF command, therefore it supports undo/redo and correctly notifies the editor to
 * show a dirty state.
