Explore Walk-able space (ground plane) set up and definition within Unity

[trentwirth]

In order to script the Dot so that it "jumps" to a new space, it needs to jump only into "walkable" spaces. The Quest lets you define your "play space", but I (@trentwirth ) don't know if we need to use this in our experiment or not. Questions:

• [ ] do we need the "play space" to run the experiment? can we ignore it?
• [ ] what are all the ways we can define the walkable space? Can we center it on an aruco marker? Something else?
• [ ] quest safety settings?

What Trent would like to do:

• draw the play space in the lab
• take the definition of that play space and use it as the "possible" location for a new dot position

  question then: is the play space an object in Unity that we have access to???

@bradencollier thinks that the playspace's center point is 0,0,0 of the "game", but if it's not there is also a command that can be used to center the game on the playspace.

Next step with this is probably to test it.
