A clickable button, that will call a function.
These are the key to starting an interactive application.
The GUI is looping, waiting for something to happen.
A button click is the classic way to start interacting with a GUI.

Whenever any function is called by the GUI, the title of the widget that called it is passed as a parameter.
That way, multiple widgets can use the same function, but different actions can be performed, depending on the name passed as a parameter.


    from appJar import gui

    # the title of the button will be received as a parameter
    def press(btn):

    # 3 buttons, each calling the same function
    app.addButton("One", press)
    app.addButton("Two", press)
    app.addButton("Three", press)
