* A radioButton is a list of toggles that can be turned on or off. radioButton is of type
* ControllerGroup, therefore a controllerPlug can't be set. this means that an event from a
* radioButton can't be forwarded to a method other than controlEvent in a sketch.
*
* a radioButton has 2 sets of values. radioButton.getValue() returns the value of the active
* radioButton item. radioButton.getArrayValue() returns a float array that represents the active
* (1) and inactive (0) items of a radioButton.
