echo_off

This is a rust library for adjusting the terminal echo property. For instance, when reading a password from the user you may want to turn echo off, and then back on again afterwards.

Not tested on any machines but my own gnu-linux ones.

Turn off echo with:

    let mut termios: Termios = Termios::new();
    termios.echo_off();

Then later:

    termios.echo_on();
