Wrap in a node.js package

[daanporon]

All these scripts are the result of our own research we did into HF. We created them on the go and now that we better know how all of these things work we should refactor this and better integrate all of these scripts. Maybe create a node package for this ...

Let's start by creating a npm wrapper around it calling the individual scripts and then start by refactoring every script one at a time.

• Use yargs for exposing + documenting the command?
• Use npm for versioning + distributing the cli
