Example Overview:
	This example uses the Timer Service to access three general purpose timers,
	gptimer0, gptimer1 and gptimer2.

	This example also uses the callback functionality of the timer service.  When
	each of the configured timers expires a function is called to enable the
	corresponding LED.

	The Timer0 is half the frequency of the Timer1, and will toggle the first
	LED in the bank of six LEDs (LED 1).

	The Timer1 is half the frequency of the Timer2, and will toggle the second
	LED in the bank of six LEDs (LED 2).

	The Timer2 occurs most often, and will toggle the third LED in the bank of six
	LEDs (LED 3).

	When the program starts, the Timer Service is enabled and after the timers are
	configured the LED's will flash at varying intervals, as described.

	This example is based on one of the interrupt manager examples, IntMgrTimerExample, 
	but instead of manually programming the general purpose timers, the Timer Service 
	in the System Services library is used.
