CLI command to create a new isograph config

[rbalicki2]

Also we should update the quick start accordingly

I've got experience with clap and am interested in this issue.

I noticed you're using structop but that project was essentially consumed by clap a while back and the project is in maintenance mode. Any opposition to moving to clap as part of this CLI improvement, or are you deliberately avoiding the extra overhead (and features) of clap?

• 100%, happy to migrate to clap! There is no concrete reason we're using structopt.
• Love it! Let's hop on a call at some point in time and discuss details. Can you join the #isograph channel on the discord, where we can figure out a good time (https://discord.gg/kDCcN3EDR6)?

The gist of this (poorly written) issue is:

• I would like to add a subcommand, along the lines of https://nextjs.org/docs/pages/api-reference/create-next-app that asks you several things. We can provide default values (or lack of values) for the other Isograph config items:
  • where is the graphql schema,
  • where is the folder where Isograph components are located
  • should we modify the tsconfig.json (to add "@iso": ["./src/components/__isograph/iso.ts"],)
  • should we create or modify .babelrc.json?
• this CLI command should create the isograph.config.json and optionally modify the other files.
