* Truncated JMRI WiThrottle server implementation for DCC-EX command station
* Credit is due to Valerie Valley RR https://sites.google.com/site/valerievalleyrr/
* for showing how it could be done, but this code is very different to the original
* implemenatatin as it is designed to run on the Arduino and not the ESP and is
* implementation as it is designed to run on the Arduino and not the ESP and is
* also calling directly into the DCCEX Api rather than simulating JMRI text commands.
