/** @class DataLogger 
  
  @brief Logs all message and infos between the services
  
  This is the main logging class facility. 
  It derives from StateMachineDim and DimInfoHandler. the first parent is here to enforce 
  a state machine behaviour, while the second one is meant to make the dataLogger receive
  dim services to which it subscribed from.
  The possible states and transitions of the machine are:
