[Curriculum] Week 4 - State with fun-mode

[vsmart]

Learning goal

The topic of week 4 is to introduce state using Quil's functional mode. Ideally, also incorporate the user interaction learnings from the week before. Idea: make a simple counter where clicking a button increases a number.

Todo in preparation

• Build a simple quil sketch that helps showcase the goal.
• Fill in the Readme with instructions on how to build this sketch, and explaining the core ideas.
• Open a PR to push your solution sketch to the [week-4] folder.
• Think of bonus ideas to expend on the sketch - add these to the readme.

I think this is a really important lesson.

This lesson needs to provide examples of how to do the earlier stuff in a "fun" way (i.e. via the state hashmap)!

The trick will be explaining not just how to do it but why...
