WANT: code that can import CSV files.

[gitclem]

After much gnashing of teeth, I now realize I can modify the connect.py code so that it can import CSV files. I will do this and maybe make a PR when I'm done.

So this is a feature request that I will try to fulfill myself.

This issue is for a: (mark with an x)

- [ ] bug report -> please search issues before submitting
- [ X] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

connect.py only creates vertexes and edges that are hard coded instead of importing data from CSV files.

Any log messages given by the failure

Expected/desired behavior

I want something like:
python import.py vertex.csv edge.csv

OS and Version?

macOS 10.15.7 (Catalina)

Versions

Mention any other details that might be useful

The Cosmos Gremlin world would be nicer if it was easier for newbies to do simple things, like import their data from elsewhere.
