Command-line Parsing

[Mierdin]

We need to implement a module that parses command-line arguments and parameters. The base command can be something like bdot, and then after that we can put in some subcommands like bdot earth, and that will output some data about the Earth API.

We might also want some optional parameters

Do we want to use something like Click. Jeorry suggested this in the Slack channel, but I had been thinking about it too and wanted to second it.

It seems like a reasonable framework for setting up commands and subcommands.

Personally I would recommend we go with the canonical Python approach whenever possible (i.e. stdlib) so we can include as many folks as possible. In this case it would be argparse, which is actually not that bad to work with.

I'm good with argeparse. I was going to tackle the patent API first as a warmup.

I am good with argparse too! I will actually get working on setting up the cli structure (more on that in another issue).
