// SYNTAX:
//   TimerFreeTone( pin, frequency, duration [, volume ] ) - Play a note on pin at frequency in Hz for duration in milliseconds.
//     Parameters:
//       * pin        - Pin speaker is wired to (other wire to ground, be sure to add an inline 100 ohm resistor).
//       * frequency  - Play the specified frequency (should work fairly well in the 100 to 15000 Hz range).
//       * duration   - Set the duration to play in milliseconds. Range: 0 to 65535 (65.5 seconds).
//       * volume     - Optionally set the tone volume level (from 1 to 10), defaults to full volume (10).
