*
* Create a smart button class with an invoke method that's
* to be called when the button is pressed.
*
* Subclasses override the invoke method to define
* specific behavior.
*
* That would allow things like load and save frames
* to be almost exactly the same -- one could inherit
* from the other and override addButtons, etc
