Add prompts npm package for command line prompt

[Rahul]

Hi,

Like we have

minimist as global argv for command-line arguments, and other useful packages like which and os, I think prompts will be a nice add.

Current question() command is limited, where prompt package has many use cases, and features. And looks very good and interactive in terminal.

Thanks :)
