/**
 * Session3 Project
 * Upon Startup:
 * ** create a rainbow with the LEDs.  hint:  b.rainbow(10);
 * ** set the Button LEDs (at position 3,6,9,12) to Red
 * ** subscribe to an event called, 'showRainbow' that shows rainbow
 *    and returns the LEDs to their previous color.  Either red or Green
 * ** create a function call 'doReset' that will reset the LEDs to Red
 * 
 * Loop:
 * ** Detect when a button is pressed
 * ** publish an event called:  'button1', 'button2', 'button3', 'button4'
 * ** Light each LED associated with the button to Green
 * ** Publish the 'buttonx' event for each button press
 * 
 * Note:
 * ** make sure you only publish one event per button press
 *
