#       The way to think about this is that each radio button menu
#       controls a different variable -- clicking on one of the
#       mutually exclusive choices in a radiobutton assigns some value
#       to an application variable you provide. When you define a
#       radiobutton menu choice, you have the option of specifying the
#       name of a varaible and value to assign to that variable when
#       that choice is selected. This clever mechanism relieves you,
#       the programmer, from having to write a dumb callback that
#       probably wouldn't have done anything more than an assignment
#       anyway. The Tkinter options for this follow their Tk
#       counterparts:
#       {"variable" : my_flavor_variable, "value" : "strawberry"}
#       where my_flavor_variable is an instance of one of the
#       subclasses of Variable, provided in Tkinter.py (there is
#       StringVar(), IntVar(), DoubleVar() and BooleanVar() to choose
#       from)
