Scenario 2

This is not ready for merge. I just want to get some eyes on it.

I believe `*/` will find an object `objectName` of any root level parent and `//` will find the node anywhere in the scene. I ran into the problem looking for `*/radio` when it was attached to the rover. I tried adding `//` which made it this: `*///radio`, which somehow returned the radio object 3 times. Thus, I changed this piece of code.
