Implements a button with added menu functionality.

There are 2 modes of operation available.

If the button is split, a menu will popup when the menu area of the button is clicked. Activating a menu item changes the functionality of the button by having it emit a additional signal when it is clicked. The signal emitted when the button is clicked, is the ItemClicked(Int_t) signal with a different fixed value for the Int_t that corresponds to the id of the activated menu entry.

If the button is not split, clicking it will popup the menu and the ItemClicked(Int_t) signal will be emitted when a menu entry is activated. The value of the Int_t is again equal to the value of the id of the activated menu entry.

The mode of operation of a SplitButton can be changed on the fly by calling the SetSplit(Bool_t) method.
