 * <p>It is important to name your plugin like *Plugin.java, because the
 * CDKPluginManager used by Jmol and JChemPaint will only load
 * plugin classes which name end with 'Plugin'.
 *
 * <p>The plugin interacts with the application in which it is loaded
 * using an <code>CDKEditBus</code> object. Check its API to see how to
 * interact with the application.
