Output matrix values to a number box

To output matrix values to a number box, use metro 1000 to bang a counter object, and use that output as the matrix coordinate for the getcell message. Please note that the third outlet of counter does not send out a bang unless you tell it to (with a carrybang message). It sends out a 1 when the counter reaches its maximum, and a 0 on the next output. This causes a double trigger.
