//TODO:  Needs to return to a black screen - not to exit...

    // i.e.: operational sequence
    //    1) starts in a black screen
    //    2) we 'start' with keypress "s" the entire set of analyses
    //    3) at any point we need to be able to restart /
stop-return-to-black / trigger each analysis individually
    //    4) should end in black screen as well
    //    5) final kill button
