Implement CLI editor

[ctengel]

This implements a portion of #8

• $ tbt-edit con add p1 p2
  • -i interactively prompt for distance, tracks; display average len etc
  • -l specify length
  • -t... specify track colors
  • if no options do not specify any
• $ tbt-edit con mod p1 p2
  • -l specify length
  • -t... specify track colors
  • if no options, go interactive
• $ tbt-edit con del p1 p2
• $ tbt-edit lengths - bulk modify lengths
• $ tbt-edit stats - summarize stats
• $ tbt-edit show - output each city with its connections, lengths, etc
• $ tbt-edit point del pt
  • -f delete even if there are connections

Need to move #10 stuff into this CLI.

[ctengel]

• click seems too bulky!
• argparse could be an option
• docopt maybe
• also see google fire
• invoke? probably not

lets just start with argparse unless it drives us nots

other question

• setup.py ?
• setup.cfg ? https://packaging.python.org/en/latest/tutorials/packaging-projects/
• pyproject.toml - https://peps.python.org/pep-0621/#specification https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml/ https://github.com/pypa/setuptools/issues/3214
