/**
 * XnpCount is an extension of CntToLedsAndRfm that can take network
 * reprogramming request.
 *
 * CntToLeds maintains a counter on a 4Hz timer; it displays the lowest
 * three bits of the counter value on its LEDS. The red LED is the least
 * significant of the bits, while the yellow is the most significant. It
 * also sends out each counter value in an IntMsg AM packet.
 * 
 * XnpCount stops Counter component when it receives network
 * reprogramming request to make the application not compete
 * for radio resources with network programming. XnpCount starts
 * Counter again after it is notified of successful network
 * reprogramming termination.
