Pathless location traversal

[Jason-Ku]

Motivation:

• Tourgraph may not be completely connected (some locations are really far, ex: dairy farm, or we just don't have video for certain paths yet)
• Convenience - Very likely that a good number of people will want to quickly move to other places and do not care about the video walk through (at least, not every single time). Also, you will almost certainly want to go to certain places without having to go through every single node on the way there (maybe you want to get back to where you started after you've went through a bunch of locations?)
• Possibly start somewhere specific that you are interested in versus a default location
• Cool feature
• Show you where you are overall

Implementation details:

• Early implementation will likely be a simple list of locations
• Final implementation will likely be an interactive map where you can click on locations
  • Highlighting a location on the map should show some metadata to aid with user selection (name of location, anything else?)
  • "You are here" icon?
• Access map via fixed icon/button on the viewport (?), probably not an overlay
