    \brief macro to generate debug messages

    \param level the debug level, please respect the following guidelines:
      - 1 is for critical errors users may find it difficult to understand but
        are still quite clear
      - 2-4 is for stuff developers are interested in in general, but
        shouldn't fill the screen with useless low level verbose stuff
      - 5-6 is for errors you may want to track, but only if you explicitly
        looking for additional clues
      - 7-10 is for informational stuff

    \param body the debug message you want to send, should end with \n
