  - ### addEventListener

    public static <L> void addEventListener(Object eventSource, Class<L> listenerType, L listener)
    Adds an event listener to the specified source. This looks for an "add" method corresponding to the event type (addActionListener, for example).
    Type Parameters:
      `L` - the event listener type
    Parameters:
      `eventSource` - the event source
      `listenerType` - the event listener type
      `listener` - the listener
    Throws:
      `IllegalArgumentException` - if the object doesn't support the listener type

  - ### bindEventsToMethod

    public static <L> void bindEventsToMethod(Object target, String methodName, Object eventSource, Class<L> listenerType, String... eventTypes)
    Binds an event listener to a specific method on a specific object.
    Type Parameters:
      `L` - the event listener type
    Parameters:
      `target` - the target object
      `methodName` - the name of the method to be called
      `eventSource` - the object which is generating events (JButton, JList, etc.)
      `listenerType` - the listener interface (ActionListener.class, SelectionListener.class, etc.)
      `eventTypes` - the event types (method names) from the listener interface (if none specified, all will be supported)
