Add meta files

[shanecelis]

Hello Wenzy--,

Really cool project you have here! The mind boggles at the possibilities. Thank you for sharing.

I got the scene working on my machine. It didn't work out of the box because the repo doesn't include any of the .meta files. Perhaps your meta files aren't marked as visible? Without the meta files, nothing linked from a scene will stick. Lots of missing script references in the scene.

I'm using Unity2019.3.0f6 which is probably later than yours judging by the change in serialization version (see below).

I'm not sure I'd encourage you to accept this pull request because it might require you to upgrade your version of Unity. It may actually be better just to ignore this pull request (I won't be offended; it's what I recommend!) and find a way to commit your own .meta files.

Thanks again for this really cool piece of tech!

Wow~ Thanks Shane for reminding me! I didn't notice I have to add the .meta files. Maybe I will do a simple update soon.
