    DefaultTeslaAether logs a bunch of stuff to System.out, which is annoying.  We choose to disable that

    This has implications for other things that are running in parallel to this.  Namely, if anything else also grabs
    a reference to System.out or tries to log to it while we have things adjusted like this, then they will also log
    to nothingness.  Fortunately, the code that calls this is single-threaded and shouldn't hopefully be running
    alongside anything else that's grabbing System.out.  But who knows.
