Refactoring/redesign is needed to let more cli extensions

[yurilaaziz]

I started using this library for an internal project at work (a cli to generate python code base).

below a list of features I could add it here:

• Add jinja2, to include answers in later questions.
• Looping over a list of questions and return a list of answers.
• Conditional statements, Show or hide questions based on previous question' answers
