* \brief Main application function
*
* This function ensures that the hardware and drivers are initialized before
* entering an infinite work loop.
*
* In the work loop, the maXTouch device is polled for new touch events and any
* new event is passed on to the user interface implementation for processing.
* The loop then attempts to enter sleep.
*
* The user interface processing itself is not started by the work loop, but by
* the USB callback function for start of frame.
