Itinerary on the Go app for iPhone and iPad

This mobile app displays trips and their itineraries. It is a view only app.

The app can load itineraries from static yaml files. A database or cloud account are not required; however, the yaml files must be accessible via the internet.

Usage is simple:
1. Launch the app
2. Add itinerary Url (via copy & paste or scanning a QR Code)
3. View itinerary

Example use cases:
- Tour group members can view an itinerary on their mobile devices
- Walking tour guide: The tour guide has prepared the yaml file and carries its Url in printed form as a QR Code. When customers join the walking tour, they can download the app and scann the QR code, in order to see the scope of the tour and follow it.
- On a trip with friends or the larger family, all participants are on the same line regarding the next steps and stops
