Add comprehensive Javadoc documentation for public APIs

- Document core classes: VSTask, VSMessage, VSInternalProcess
- Document event interfaces: VSAbstractEvent, VSCopyableEvent, VSTime
- Document timestamp events: VSTimestampTriggeredEvent, VSLamportTimestampEvent
- Document protocol framework: VSAbstractProtocol methods
- Document VSSimulator and VSRegisteredEvents
- Add detailed method descriptions with parameter and return value docs
- Include usage examples and cross-references between related classes

 /**
- * The class VSRegisteredEvents. This class is responsible to manage all
- * events. It manages the event classnames, the event shortnames and the event
- * names. It also checks if a protocol (which is an event as well) has
- * variables which are editable through the GUI of the simulator.
- *
+ * Registry and manager for all available events and protocols in the simulator.
+ * This class provides a centralized location for:
+ * <ul>
+ *   <li>Registering event and protocol implementations</li>
+ *   <li>Mapping between class names, short names, and display names</li>
+ *   <li>Identifying which protocols have editable parameters</li>
+ *   <li>Managing client/server variable metadata for protocols</li>
+ * </ul>
+ * 
+ * <p>All events and protocols must be registered in {@link #init(VSPrefs)}
+ * to be available in the simulator. The registry uses reflection to discover
+ * protocol properties and determine which ones expose editable parameters.</p>
+ * 
+ * <p>This is a static utility class and cannot be instantiated.</p>
