Documentation
This is the web UI of the noelan app.
Every "page" is just setting the whole "<body>"'s innerHTML (see setPage* functions). This way
we can avoid creating a network request for each page.
Data is cached to local storage so that we only need to send requests to sync the data.
The `global_all_data` object has all the data necessary for the application to work.
TODO(luca): Get rid of PicoCSS, because it does not make a good responsive UI.
