Class SenseHandler receives input from a (Robocup Simulation) server(through an instance of Connection). The class contains methods to parse theincoming messages and sends these to the WorldModel accordingly. After thisclass is instantiated, a specific thread must call the function sense_callback.This thread will then automatically call handleMessagesFromServer() which loopsforever. In this way all messages are received and parsed (since thereceiveMessage from the Connection blocks till a message arrives). Other threadscan think about the next action while the SenseHandler sends the new informationto the WorldModel. */class SenseHandler {  WorldModel     *WM;        /*!< Worldmodel containing all data of the match */  ServerSettings *SS;        /*!< ServerSettings with all server settings     */  PlayerSettings *PS;        /*!< PlayerSettings with all client settings     */  Connection* connection;    /*!< Connection with server to receive messages  */  int         iTimeSignal;   /*!< Wait time (microsec) before sense calls act */  int         iTriCounter;   /*!< Used to indicate when see message will arive*/  int         m_iSeeCounter; /*!<!
