- Introduce some methods in the rails SportSession model to get SportSessions of a user (confirmed or not confirmed)
- Separate Running Sessions in View: Upcoming, Past, Invitations (Confirming invitations not yet implemented)
- RunningsController::index and SportSessionController::index don't need to access Cybercoach, all data is loaded from own DB
- Table to display the various sessions (upcoming, past, invitations) will go into a partial view
