/*! Class SenseHandler receives input from a (Robocup Simulation)
    server (through an instance of Connection). The class contains
    methods to parse the incoming messages and sends these to the
    WorldModel accordingly. After this class is instantiated, a
    specific thread must call the function sense_callback.  This
    thread will then automatically call handleMessagesFromServer()
    which loops forever. In this way all messages are received and
    parsed (since the receiveMessage from the Connection blocks till a
    message arrives). Other threads can think about the next action
    while the SenseHandler sends the new information to the
    WorldModel. */
