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

I've added extensive online help to PyTrain. Here are some examples:

(legacyEnv) davids@Sprucewood-iMac PyLegacy (master) % src/cli/pytrain.py
Sending commands directly to Lionel LCS Ser2...
Listening for client connections on port 5110...
PyTrain, Ver 0.1
>> ?
usage: [h] [accessory | effects | engine | halt | lighting | route | switch | quit]

Valid commands:

options:
  h, help    show this help message and exit
  accessory  Issue accessory commands
  effects    Issue engine or train effects commands
  engine    Issue engine or train commands
  halt      Emergency stop
  lighting  Issue engine or train lighting effects commands
  route      Fire defined routes
  switch    Throw switches
  quit      Quit PyTrain

Commands can be abbreviated, so long as they are unique; e.g., 'en', or 'eng' are the same as typing 'engine'.
Help on a specific command is also available by typing the command name (or abbreviation), followed by '-h',
e.g., 'sw -h'
>> św -h
usage: Fire specified switch (1 - 99) [-h] [-t|-o|-a] Switch Number

positional arguments:
  Switch Number      switch to throw

options:
  -h, --help         shows this help message
  -t, --through      Throw Through
  -o, --out          Throw Out
  -a, --set_address  Set switch address
