This block creates a variable toggle button. Leave the label
blank to use the variable id as the label. A toggle button
selects between two values of similar type, but will stay
depressed until clicked again. The variable will take on one
value or the other depending on whether the button is pressed
or released. This button will also produce a state message
matching the set values.
