Better documentation and organisation 📝

Also included are a couple of bug fixes:

• Data was incorrectly completed when only viewing one day, resulting in half the graph being "empty"
• Title of the daily graphs got displayed on the EDA graph only, but should be on the stress algorithm graph (if included)

And some efficiency improvements:

• Reading in stress algorithm models in constants, instead of every time new predictions are being loaded
