added class property "inclusive"; fixed minor bug in peek; revised method vector_obj_op2; implemented method vector_obj_op3; implemented methods start_criteria and stop_criteria, changed existing code at start_retrieve, stop_retrieve, set.start, set.stop, load; fixed stupid bug at set.stop; added useful feedback to startstop_retrieve_update; implemented method data_edges, relevant only to loading the data; in the save method: added input parameter to force recomputing data, added trap for invalid data, updated log output; in the load method: do not update start/stop if this is a plot method, fixed bug triggered by time-independent data; implemented method operation, to handle simple multi-source data operations
