Create Save/Load State UI and Functionality

[prepsure]

A website UI concept was shared by @wowannie, shown below. It shows how users could navigate to and from pages and interact with different features.
Hi hopefully I'm doing this right! My idea was to have a sandbox with different tools like a ruler or a ball and ramp that could be selected to be used in the workspace. Premade experiments could possibly be an option as well, along with a teacher page where the teacher could limit the tools that a student would use and possibly add directions.

An idea I had was that the workspace could have a similar UI to projects in desmos, where users can make and share projects with links. The user would also be able to see projects they have in local storage on a sidebar, either by making them themself or loading them from a teacher or friend through a code.

Upon clicking share, a code would be generated for the sim. Maybe this code could store all the sim data so it can be generated when the user inputs it instead of needing to store it in a database. Of course, the codes would need to be really long to contain all of the information for each object.

Saving the current state as part of the URL is implemented in 2649aba. The links are super long, as @presssssure predicted.

A basic version of the sandbox is at https://pensive-galileo-df7257.netlify.app/experiment-create. It doesn't yet let you choose tools, but you can create, edit, and delete objects.
