Determine we should manage cli flags

[AlexGaiser]

I have seen several different ways flags and inputs are managed in the different repositories we have been researching

In the addfiles CLI project I created several helper methods. We could potentially create our own library to manage flags or use one of the following existing libraries:

• command-line-args
• commander
• yargs

I have read a few reddit comments that say that commander is messy.

Closing because we have chosen yargs as our args management tool.
