echo -> clear screen / home position

Use this for clear screen:

    echo -ne '\033[2J'

and this for return to home position:

    echo -ne '\033[2H'

The latter is useful for running a command many times per second, and
observe the output:

    while sleep .05; do echo -ne '\033[2H' ; ./MY_COMMAND ; done
