Creates the basic framework for the SCED introduction/training tour. As this will be a large feature, this is intended to checkpoint
progress and work.
What's here:
- Basic tour script definition
- Script UI creation, camera handling, and flow
What's not here:
- Multiplayer support. Everything is currently locked to white.
- Final UI. Most UI is placeholder and will be updated later.
- Extra script capability such as higlighting objects, explicit positioning, etc.
