Add user interaction functions?

[killercup]

E.g. using https://docs.rs/dialoguer

I usually only add "interaction" using CLI arguments. I'd be interested to hear what your use cases are.

Todo:

• Choose which features are commonly needed
• Design an API that exposes the commonly used features in a very simple manner
• Document this API with add examples/doc tests if possible
• Add a full-featured "cook book" example (cf. Publish fancy guides/docs #16)

As an example - the NodeJS package Inquirer is a really good implementation of user interaction in cli applications - having a rust library that gave similar options would be excellent, although a library of that size would probably be better as a separate lib (not included in quicli).
