50 * This editor is used to open a trace in the Events view
51 * and set the trace as the current experiment.
52 * It intercepts the IGotoMarker adapter and dispatches
53 * the handling to the Events view' events table.
54 * The editor then closes itself and hides the
55 * editor area if no other editor is open.
