/*
	This example demonstrates how the PushEventButton captures each individual
	button press as discrete events.  It does not matter how long the button is
	pressed down or released.  Only the transition between pressed and released
	is captured.

	The button should be wired such that when pressed, the "buttonPin" is
	connected to ground.

	The LED should be wired with the "ledPin" to the positive lead and the
	negative lead should be connected to ground.  A current limiting resistor
	should be used.
