Add eslint base rules to new projects

[rglover]

Would like to have this so we can handle linting of code for undefined variables.

[rglover]

This should be conditional in the CLI.

This should be a very simple, easy to delete thing like this:

extends:
  - eslint:recommended
parser: "@babel/eslint-parser"

Just add an .eslintrc.yaml file to the root and be done with it. That can be customized or deleted per the developer's wishes.
