+/**
+* The MySensors Arduino library handles the wireless radio link and protocol
+* between your home built sensors/actuators and HA controller of choice.
+* The sensors forms a self healing radio network with optional repeaters. Each
+* repeater and gateway builds a routing tables in EEPROM which keeps track of the
+* network topology allowing messages to be routed to nodes.
