    This is a quite efficient and easy way to have some debug messages
    in your code. It is possible to disable this while run or while
    compile time in as fine steps as you like.

    -# while compiletime: to leave all the messages with a debug-level
       < x out of the programm compile with -DDEBUG_LEVEL=x

    -# while runtime: set the environment variable to the value you
       prefer.

    -# also it is possible to specify this directly in your code using
       the CheckRuntimeDebugLevel function
