+/**
+ * MoteAttributes used to store mote attributes for debugging and statistics
+ * The interface is write-only: the simulated Contiki has no knowledge of current attributes
+ * with other motes. The Contiki application can, however, add and remove attributes.
+ *
+ * A Contiki application adds/removes a relation by outputting a simple messages on its log interface,
+ * typically via printf()'s of the serial port.
+ *
+ * Syntax:
+ * "#A <Attribute Name>=<Attribute Value>"
+ *
+ * Example, add an attribute sent and set its value to 41
+ * "#A sent=41"
+ *
+ * Example, remove the attribute sent
+ * "#A sent"
+ *
