31  //! A class that is able to redirect all output to a openGL-Shell, and that one can use to input some commands
32  /**
33   * the major idea is, that all the Output can be redirected to the Shell,
34   * and does not have to be displayed to the opening Shell, this is good,
35   * for developers using Windows, where all output is otherwise redirected
36   * to stdout.txt
37   *
38   * Furthermore the Shell should enable us, to input some simple commands
39   * Each Class can check itself in to the Shell, and listen for commands.
