Refactored codebase

[liamzebedee]

Here I'm attempting to refactor the codebase. The previous iteration was largely a monolith of two files - the frontend app and the simulation model.

Some details of the refactoring directory structure are in REFACTOR.md.

The model file was extracted into the following:

• Simulation - containing the functions modelling insulin and glucose release, as well as the discrete timestep simulator
• InsulinPumpModel - containing the model of the insulin pump's settings, and relevant helpers for parsing it from text
• BodyMetabolismModel - containing the model of the body's metabolism.
• event_helpers - helpers for parsing event strings into Event effects, which are passed into the simulation.

The frontend file was refactored into the following:

• Plotly helpers - for rendering the Plotly graph, and converting between date formats
• form helpers - this just contains the debouncers
• compose helper - this is a functional helper, used by frontend and model.

Originally, the goal was to refactor frontend state. During this iteration, I realised that the state was a reasonable contained concern, compared to the rest of the codebase. Hence, the project structure was refactored instead.

Declining because it’s getting stale
