/**
* 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"
