IoTT's video: Amp Meter for DCC EX Video 103

An accurate measurement of the track current would be a useful feature for any command station. Since the DCC EX command interface provides a function for current reporting, I thought it would be no big deal to add an amp meter to the RedHat Shield web page and update it say every half a second or so.
