* @brief Resets Module, configures this device to be a Zigbee Coordinator, and displays any messages

* that are received. If the message contains a known object-identifier (OID) then parses the

* contents of the OID. Also displays received value to RGB LED and allows user to use the pushbutton

* to select which OID is displayed on the RGB LED.

*

* Uses the AF/ZDO interface.
