[x3d-public] Someone please double check my work, Re: exporting Hierarchies in Blender X3D export

[John Carlson]

Making this small change to the Blender X3D export plugin is revealing. I'm
hoping someone with previous Blender submission experience can do a pull
request, but I will try.

$ git diff .
diff --git a/io_scene_x3d/export_x3d.py b/io_scene_x3d/export_x3d.py

So there are several "EMPTY" objects which look like Transforms in glTF.
I'm not sure what to do for those.

And yes, I'm working on ARMATURE!
