    Thread design:
    Threads run in a while loop, and the while checks if the condition is not set. If the condition for finishing is set, it will terminate by finishing the run function.
    So: Lesetrad function as usual. FletteTrad wait for the conditions: InsertertedThread condition, sent by LeseTrad, lock available, and terminate = false.
    Terminate is a bool variable, not a condition. Set terminate to true, and waiting threads will finish
