I had several classes that I had not committed. I removed those and
fixed the TestApplication since it was referencing some of those
classes.
Added a multi-view test shell. It looks like creating simultaneous 3D
views with JavaFX may be much easier than with jME, although these views
don't have any actual 3D components yet.
Added 3d components to the views but encountered a bug where the "z"
order of rendered objects is affected by the order in which they are
added. In other words, two boxes added next to each other are rendered
as if the second one is "in front" of the first.
You must use depth buffering for the Scene.
To do so, you have to use one of the longer constructors for Scene.
