+/**
+   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.
