Reply to "Python code to issue TMCC, Legacy, and PDI Commands"

Some quick screen shots. I have to think a bit about syntax...

http://127.0.0.1:5000/train/20 -->
{
  "control": "Legacy",
  "direction": null,
  "labor": 12,
  "max_speed": null,
  "momentum": 0,
  "road_name": "Delaware & Hudson",
  "road_number": "0020",
  "rpm": 0,
  "scope": "train",
  "smoke": null,
  "speed": 0,
  "speed_limit": null,
  "tmcc_id": 20,
  "train_brake": 0,
  "year": null
}

http://127.0.0.1:5000/acc/15 -->
{
  "block": "on",
  "road_name": "Upper Main North Power District",
  "road_number": "0015",
  "scope": "power_district",
  "tmcc_id": 15
}

  "last_loco_rl": 255,

  "tmcc_id": 50
}

http://127.0.0.1:5000/acc/50
{
  "road_name": "Upper Main West",
  "road_number": "0050",
  "scope": "sensor_track",
  "tmcc_id": 50
}

http://127.0.0.1:5000/switch/1 -->
{

  "road_number": "0001",
  "scope": "switch",
  "state": "thru",

}

I'm trying out the flask-restful package. It only took about 40 lines of code to generate this output. If others have suggestions for restful-api frameworks that they've used in Python, I'd love to hear about them.

What's interesting is that I've basically written a wrapper around the PyTrain CLI, I can literally issue any  dmcc/legacy command I want to. I will probably write simplified POST handlers for speed, direction, bell, horn, and any other common engine commands, but then I'll add an endpoint that takes a CLI command, giving me access to the entire Lionel command set.
