Renders all your gpx files in the browser!
Run backend/backend.py <PATH_TO_GPX> (requires python 3+). PATH_TO_GPX is optional, if no argument is specified the default behaviour is to look for .gpx files in the folder data. --from-strava is an optional argument, if provided the files in PATH_TO_GPX will be treated as a Strava export and converted to gpx.
Open index.html in browser.
