/*
 * ActionButton example
 * Jeff Hoefs
 * 11/3/11
 *
 * This example demonstrates a few diffrent ways to use the ActionButton
 * library. You can attach event listeners, or poll for the changes in 
 * button state.
 *
 * Note that you must specify the button mode as the 2nd paramter of the
 * ActionButton constructor (PULL_UP, PULL_UP_INTERNAL, PULL_DOWN)
 * according to how you have wired the button to your Arduino.
