To implement the sioTinyTimber driver, the following must be done:
* Instantiate and initialize SysIO object:
   SysIO  sio0 = initSysIO (SIO_PORT0, &app, buttonPress);
* Create callback method ie. "buttonPress"
* Install interrupt handler:
   INSTALL(&sio0, sio_interrupt, SIO_IRQ0);
* Call init function SIO_INIT in startApp.
   SIO_INIT(&sio0);
   
CURRENT PROBLEM
===============
* Trying to measure time differences between subsequent button presses. Taking the difference between the CURRENT_BASELINE and the prvious saved CURRENT_BASELINE yields a value that toggles back and forth, and always increments????
 Should a Timer object be used?
 How did we measure WCET in the previous course??
