    - #### 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)
