[x3d-public] Possible error in X3dToNodeJS.xslt? LayerSet handling, multiple Mantis issues, class simplification for Java/Node SAI

Sat May 30 19:11:43 PDT 2020

What I've seen is the X3dToJava.xslt does the "addLayerSet" properly.

So we need to upgrade the various stylesheets to how X3dToJava.xslt does it.

We can work on this Monday.  Thanks!

John
