Mikrotik - router audio alignment script.

This helpful script was given to me.  It was sent to me by WISP-Router (http://www.wisp-router.com/).  Casey told me it was sent to them by one of their customers.  It will create a beep that changes frequency as the alignment gets better/worse.  Requires (of course) a MT router with a speaker onboard.

:local beep “10ms”;
