// 	 Class : ButtonEventDataTransition
// Description : A ButtonEventDataAttribute is a collection of buttons
//               that have been pressed recently, in the order they
//               were pressed.  The ButtonEventDataTransition does
//               nothing, since there's no sensible transformation to
//               apply to this collection of buttons.
